Google : history and everything you need to know.

Google 

Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, and software. Most of its profits are derived from AdWords, an online advertising service that places advertising near the list of search results.
Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University. Together, they own about 14 percent of its shares and control 56 percent of the stockholder voting power through supervoting stock. They incorporated Google as a privately held company on September 4, 1998. An initial public offering followed on August 19, 2004. Its mission statement from the outset was "to organize the world's information and make it universally accessible and useful," and its unofficial slogan was "Don't be evil". In 2004, Google moved to its new headquarters in Mountain View, California, nicknamed the Googleplex. In August 2015, Google announced plans to reorganize its interests as a holding company called Alphabet Inc. When this restructuring took place on October 2, 2015, Google became Alphabet's leading subsidiary, as well as the parent for Google's Internet interests.
Rapid growth since incorporation has triggered a chain of products, acquisitions and partnerships beyond Google's core search engine . It offers online productivity software  including email, a cloud storage service  and a social networking service . Desktop products include applications for web browsing, organizing and editing photos, and instant messaging . The company leads the development of the Android mobile operating system and the browser-only Chrome OS for a class of netbooks known as Chromebooks. Google has moved increasingly into communications hardware: it partners with major electronics manufacturers in the production of its "high-quality low-cost" Nexus devices. In 2012, a fiber-optic infrastructure was installed in Kansas City to facilitate a Google Fiber broadband service.
The corporation has been estimated to run more than one million servers in data centers around the world . It processes over one billion search requests and about 24 petabytes of user-generated data each day .
In December 2013, Alexa listed google.com as the most visited website in the world. Numerous Google sites in other languages figure in the top one hundred, as do several other Google-owned sites such as YouTube and Blogger. Its market dominance has led to prominent media coverage, including criticism of the company over issues such as aggressive tax avoidance, search neutrality, copyright, censorship, and privacy.
History
Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in Stanford, California.
While conventional search engines ranked results by counting how many times the search terms appeared on the page, the two theorized about a better system that analyzed the relationships between websites. They called this new technology PageRank; it determined a website's relevance by the number of pages, and the importance of those pages, that linked back to the original site.
Page and Brin originally nicknamed their new search engine "BackRub", because the system checked backlinks to estimate the importance of a site. Eventually, they changed the name to Google, originating from a misspelling of the word "googol", the number one followed by one hundred zeros, which was picked to signify that the search engine was intended to provide large quantities of information. Originally, Google ran under Stanford University's website, with the domains google.stanford.edu and z.stanford.edu.
The domain name for Google was registered on September 15, 1997, and the company was incorporated on September 4, 1998. It was based in the garage of a friend . In January 2013, Google announced it had earned in annual revenue for the year of 2012. This marked the first time the company had reached this feat, topping their 2011 total of $38 billion.
The company has reported fourth quarter  Earnings Per Share  of $6.88 – $0.20 under projections. Revenue came in at $14.5 billion, also under expectations by $110 million.
Financing, 1998 and initial public offering, 2004  
The first funding for Google was an August 1998 contribution of $100,000 from Andy Bechtolsheim, co-founder of Sun Microsystems, given before Google was incorporated. Early in 1999, while graduate students, Brin and Page decided that the search engine they had developed was taking up too much time and distracting their academic pursuits. They went to Excite CEO George Bell and offered to sell it to him for $1 million. He rejected the offer and later criticized Vinod Khosla, one of Excite's venture capitalists, after he negotiated Brin and Page down to $750,000. On June 7, 1999, a $25 million round of funding was announced, with major investors including the venture capital firms Kleiner Perkins Caufield & Byers and Sequoia Capital. The company offered 19,605,052 shares at a price of $85 per share. Shares were sold in an online auction format using a system built by Morgan Stanley and Credit Suisse, underwriters for the deal. The sale of $1.67 bn  gave Google a market capitalization of more than $23bn. By January 2014, its market capitalization had grown to $397bn. The vast majority of the 271 million shares remained under the control of Google, and many Google employees became instant paper millionaires. Yahoo!, a competitor of Google, also benefited because it owned 8.4 million shares of Google before the IPO took place.
There were concerns that Google's IPO would lead to changes in company culture. Reasons ranged from shareholder pressure for employee benefit reductions to the fact that many company executives would become instant paper millionaires. As a reply to this concern, co-founders Sergey Brin and Larry Page promised in a report to potential investors that the IPO would not change the company's culture. In 2005, articles in The New York Times and other sources began suggesting that Google had lost its anti-corporate, no evil philosophy. In an effort to maintain the company's unique culture, Google designated a Chief Culture Officer, who also serves as the Director of Human Resources. The purpose of the Chief Culture Officer is to develop and maintain the culture and work on ways to keep true to the core values that the company was founded on: a flat organization with a collaborative environment. Google has also faced allegations of sexism and ageism from former employees. In 2013, a class action against several Silicon Valley companies, including Google, was filed for alleged "no cold call" agreements which restrained the recruitment of high-tech employees.
The stock performed well after the IPO, with shares hitting $350 for the first time on October 31, 2007, primarily because of strong sales and earnings in the online advertising market. The surge in stock price was fueled mainly by individual investors, as opposed to large institutional investors and mutual funds. The company is listed on the NASDAQ stock exchange under the ticker symbols GOOGL and GOOG, and on the Frankfurt Stock Exchange under the ticker symbol GGQ1. These ticker symbols now refer to Alphabet Inc., Google's holding company, since the fourth quarter of 2015.
Growth  
In March 1999, the company moved its offices to Palo Alto, California, which is home to several prominent Silicon Valley technology start-ups. The next year, against Page and Brin's initial opposition toward an advertising-funded search engine, Google began selling advertisements associated with search keywords. When the company changed names to Overture Services, it sued Google over alleged infringements of the company's pay-per-click and bidding patents. Overture Services would later be bought by Yahoo! and renamed Yahoo! Search Marketing. The case was then settled out of court; Google agreed to issue shares of common stock to Yahoo! in exchange for a perpetual license.
In 2001, Google received a patent for its PageRank mechanism. The patent was officially assigned to Stanford University and lists Lawrence Page as the inventor. In 2003, after outgrowing two other locations, the company leased an office complex from Silicon Graphics at 1600 Amphitheatre Parkway in Mountain View, California. The complex became known as the Googleplex, a play on the word googolplex, the number one followed by a googol zeroes. The Googleplex interiors were designed by Clive Wilkinson Architects. Three years later, Google bought the property from SGI for $319 million. By that time, the name "Google" had found its way into everyday language, causing the verb "google" to be added to the Merriam-Webster Collegiate Dictionary and the Oxford English Dictionary, denoted as "to use the Google search engine to obtain information on the Internet".
The immense popularity of the search engine has led its fans calling themselves 'Googlists' as they follow 'Googlism', the new religion. Devotees of Google have found a non-profit online organization The Church of Google, a website where they worship the search engine giant. The New York Times had discussed the topic "Is Google God?" under its 'opinion' category. On the Internet, there are many blogs that even mention the reasons why Google is God.
2013 onward  
Google announced the launch of a new company called Calico on September 19, 2013, which will be led by Apple chairman Arthur Levinson. In the official public statement, Page explained that the "health and well-being" company will focus on "the challenge of ageing and associated diseases".
As of September 2013, Google operates 70 offices in more than 40 countries. Google celebrated its 15-year anniversary on September 27, 2013, although it has used other dates for its official birthday. The reason for the choice of September 27 remains unclear, and a dispute with rival search engine Yahoo! Search in 2005 has been suggested as the cause.
The Alliance for Affordable Internet  was launched in October 2013 and Google is part of the coalition of public and private organisations that also includes Facebook, Intel and Microsoft. Led by Sir Tim Berners-Lee, the A4AI seeks to make Internet access more affordable so that access is broadened in the developing world, where only 31% of people are online. Google will help to decrease Internet access prices so that they fall below the UN Broadband Commission's worldwide target of 5% of monthly income.
The corporation's consolidated revenue for the third quarter of 2013 is reported in mid-October 2013 as $14.89 billion, a 12 percent increase compared to the previous quarter. Google's Internet business was responsible for $10.8 billion of this total, with an increase in the number of users' clicks on advertisements.
In November 2013, Google announced plans for a new 1-million-sq-ft  office in London, which is due to open in 2016. The new premises will be able to accommodate 4,500 employees and has been identified as one of the biggest ever commercial property acquisitions in Britain.
In October 2014, according to the Interbrand ranking, Google was the second most valuable brand in the world  with a valuation of $107.4 billion. A Millward Brown report from the same year puts the Google brand ahead of Apple's at #1.
Acquisitions and partnerships  
Since 2001, Google has acquired many companies, primarily small venture capital-funded firms. In 2004, Google acquired Keyhole, Inc. The start-up company developed a product called Earth Viewer that gave a three-dimensional view of the Earth. Google renamed the service to Google Earth in 2005. Google acquired Urchin Software in April 2005, using their 'Urchin on Demand' product  to create Google Analytics in 2006.
In October 2006, Google announced that it had acquired the video-sharing site YouTube for $1.65 billion in Google stock, and the deal was finalized on November 13, 2006. Google does not provide detailed figures for YouTube's running costs, and YouTube's revenues in 2007 were noted as "not material" in a regulatory filing. In June 2008, a Forbes magazine article projected the 2008 YouTube revenue at $200 million, noting progress in advertising sales.
On April 13, 2007, Google reached an agreement to acquire DoubleClick for $3.1 billion, giving Google valuable relationships that DoubleClick had with Web publishers and advertising agencies. Later that same year, Google purchased GrandCentral for $50 million. The site would later be changed over to Google Voice. On August 5, 2009, Google bought out its first public company, purchasing video software maker On2 Technologies for $106.5 million. Google also acquired Aardvark, a social network search engine, for $50 million, and commented on its internal blog, "we're looking forward to collaborating to see where we can take it". In April 2010, Google announced it had acquired a hardware startup, Agnilux.
In addition to the many companies Google has purchased, the company has partnered with other organizations for research, advertising, and other activities. In 2005, Google partnered with NASA Ames Research Center to build of offices. The offices would be used for research projects involving large-scale data management, nanotechnology, distributed computing, and the entrepreneurial space industry. Google entered into a partnership with Sun Microsystems in October 2005 to help share and distribute each other's technologies.
The company also partnered with AOL to enhance each other's video search services. Google's 2005 partnerships also included financing the new .mobi top-level domain for mobile devices, along with other companies including Microsoft, Nokia, and Ericsson. Google would later launch "AdSense for Mobile", taking advantage of the emerging mobile advertising market. Increasing its advertising reach even further, Google and Fox Interactive Media of News Corporation entered into a $900 million agreement to provide search and advertising on the then-popular social networking site MySpace.
In 2007, Google began sponsoring NORAD Tracks Santa, displacing former sponsor AOL. NORAD Tracks Santa purports to follow Santa Claus' progress on Christmas Eve, using Google Earth to "track Santa" in 3-D for the first time. Google-owned YouTube gave NORAD Tracks Santa its own channel.
In 2008, Google developed a partnership with GeoEye to launch a satellite providing Google with high-resolution  imagery for Google Earth. The satellite was launched from Vandenberg Air Force Base on September 6, 2008. Google also announced in 2008 that it was hosting an archive of Life Magazine's photographs. Some images in the archive were never published in the magazine. The photos were watermarked and originally had copyright notices posted on all photos, regardless of public domain status.
In 2010, Google Energy made its first investment in a renewable energy project, putting $38.8 million into two wind farms in North Dakota. The company announced the two locations will generate 169.5 megawatts of power, enough to supply 55,000 homes. The farms, which were developed by NextEra Energy Resources, will reduce fossil fuel use in the region and return profits. NextEra Energy Resources sold Google a twenty-percent stake in the project to get funding for its development. In February 2010, the Federal Energy Regulatory Commission FERC granted Google an authorization to buy and sell energy at market rates. The order specifically states that Google Energy—a subsidiary of Google—holds the rights "for the sale of energy, capacity, and ancillary services at market-based rates", but acknowledges that neither Google Energy nor its affiliates "own or control any generation or transmission" facilities. The corporation exercised this authorization in September 2013 when it announced that it will purchase all the electricity produced by the not-yet-built 240-megawatt Happy Hereford wind farm.
Also in 2010, Google purchased Global IP Solutions, a Norway-based company that provides web-based teleconferencing and other related services. This acquisition enabled Google to add telephone-style services to its list of products. On May 27, 2010, Google announced it had also closed the acquisition of the mobile ad network AdMob. This occurred days after the Federal Trade Commission closed its investigation into the purchase. Google acquired the company for an undisclosed amount. In July 2010, Google signed an agreement with an Iowa wind farm to buy 114 megawatts of energy for 20 years.
On April 4, 2011, The Globe and Mail reported that Google bid $900 million for six thousand Nortel Networks patents.
On August 15, 2011, Google made its largest-ever acquisition to-date when it announced that it would acquire Motorola Mobility for $12.5 billion subject to approval from regulators in the United States and Europe. In a post on Google's blog, Google Chief Executive and co-founder Larry Page revealed that the acquisition was a strategic move to strengthen Google's patent portfolio. The company's Android operating system has come under fire in an industry-wide patent battle, as Apple and Microsoft have sued Android device makers such as HTC, Samsung, and Motorola. The merger was completed on May 22, 2012, after the approval of People's Republic of China.
This purchase was made in part to help Google gain Motorola's considerable patent portfolio on mobile phones and wireless technologies to help protect it in its ongoing patent disputes with other companies, mainly Apple and Microsoft, After the acquisition closed, Google began to restructure the Motorola business to fit Google's strategy. On August 13, 2012, Google announced plans to lay off 4000 Motorola Mobility employees. On December 10, 2012, Google sold the manufacturing operations of Motorola Mobility to Flextronics for $75 million. As a part of the agreement, Flextronics will manufacture undisclosed Android and other mobile devices. On December 19, 2012, Google sold the Motorola Home business division of Motorola Mobility to Arris Group for $2.35 billion in a cash-and-stock transaction. As a part of this deal, Google acquired a 15.7% stake in Arris Group valued at $300 million.
On June 5, 2012, Google announced it acquired Quickoffice, a company widely known for their mobile productivity suite for both iOS and Android. Google plans to integrate Quickoffice's technology into its own product suite.
On February 6, 2013, Google announced it had acquired Channel Intelligence for $125 million. Channel Intelligence, a technology company that helps customers buy products online, is active globally in 31 different countries and works with over 850 retailers. Google will use this technology to enhance its e-commerce business.
The official confirmation of Google's acquisition of the Israel-based startup Waze occurred in June 2013. Waze is promoted as a "community-based traffic and navigation app".
Following the acquisition of Waze, Google submitted a "10-Q" filing with the Securities Exchange Commission  that revealed that the corporation spent $1.3 billion on acquisitions during the first half of 2013. The filing also revealed that the Waze acquisition cost Google $966 million, instead of the $1.1 billion figure that was initially presented in media sources.
The 2012 acquisition of WIMM Labs, a company that previously made an Android-powered smartwatch, was confirmed in August 2013. As of August 31, 2013, Google has not publicly commented on the news concerning WIMM Labs. The acquisition of Flutter, a creator of hand gesture recognition technology, was confirmed by the corporation in early October 2013. The reported price is $40 million and Google spokesperson stated: "We're really impressed by the Flutter team's ability to design new technology based on cutting-edge research." Flutter's technology allows users to enact hand gestures to control navigation for apps such as iTunes, Windows Media Player, and Winamp.
On January 26, 2014, Google Inc. announced it had agreed to acquire DeepMind Technologies, a privately held artificial intelligence company from London. DeepMind describes itself as having the ability to combine the best techniques from machine learning and systems neuroscience to build general-purpose learning algorithms. DeepMind's first commercial applications were used in simulations, e-commerce and games. As of December 2013, it was reported that DeepMind had roughly 75 employees. The technology news website Re/code reported that the company was purchased for $400 million though it was not disclosed where the information came from. A Google spokesman would not comment of the price. The purchase of DeepMind aids in Google's recent growth in the artificial intelligence and robotics community.
On January 29, 2014, Google announced it was selling its Motorola Mobility unit to China-based Lenovo, for $2.91bn. The company kept the extensive patent collection used to develop Android products, considered the most valuable part of the original deal. Nonetheless, the sale price was significantly less than the $12.5 billion Google had bought Motorola Mobility for. The $2.91bn price tag consisted of $660 million in cash, $750 million in Lenovo ordinary shares, and a $1.5 billion 3-year promissory note.
In March 2014, Google confirmed it had purchased the remnants of gaming startup, Green Throttle Games, which developed a Bluetooth gaming controller for Android.
In May 2014, Google announced it had purchased Quest Visual, maker of the augmented reality translator app Word Lens.
In June 2014, Google purchased satellite imaging firm Skybox Imaging for $500 million.
In July 2014, Google purchased the online music service Songza.
On September 10, 2015, Google announced to form strategic partnership with Mobvoi to bring Android Wear to mainland China.
In October 2015, Google invested in a China-based artificial intelligence  company, Mobvoi. The funding will enable the Company to further enhance its core AI technologies, and develop new consumer products empowered by AI.
Google data centers  
, Google Inc. owned and operated six Google Modular Data Centers across the U.S., one in Chile, one in Finland, one in Ireland, one in Belgium, one in Singapore and one on Taiwan. In 2011, the company had announced plans to build three data centers at a cost of more than $200 million in Asia  and said they would be operational within two years. In December 2013, Google announced that it had scrapped the plan to build a data center in Hong Kong.
In October 2013, The Washington Post reported that the U.S. National Security Agency intercepted communications between Google's data centers, as part of a program named MUSCULAR. This wiretapping was made possible because Google did not encrypt data passed inside its own network. Google began encrypting data sent between data centers in 2013.
Alphabet  
On August 10, 2015, Google announced plans to reorganize its various interests as a holding company, Alphabet Inc., with Google as its leading subsidiary. Google will continue to be the umbrella company for Alphabet's Internet interests. Upon completion of the restructure, Sundar Pichai became CEO of Google.
Products and services
Advertising  
For the 2006 fiscal year, the company reported $10.492 billion in total advertising revenues and only $112 million in licensing and other revenues. In 2011, 96% of Google's revenue was derived from its advertising programs. In addition to its own algorithms for understanding search requests, Google uses technology from the company DoubleClick, to project user interest and target advertising to the search context and the user history.
Google Analytics allows website owners to track where and how people use their website, for example by examining click rates for all the links on a page. Google advertisements can be placed on third-party websites in a two-part program. Google's AdWords allows advertisers to display their advertisements in the Google content network, through either a cost-per-click or cost-per-view scheme. The sister service, Google AdSense, allows website owners to display these advertisements on their website and earn money every time ads are clicked.
One of the criticisms of this program is the possibility of click fraud, which occurs when a person or automated script clicks on advertisements without being interested in the product, causing the advertiser to pay money to Google unduly. Industry reports in 2006 claimed that approximately 14 to 20 percent of clicks were fraudulent or invalid.
In February 2003, Google stopped showing the advertisements of Oceana, a non-profit organization protesting a major cruise ship's sewage treatment practices. Google cited its editorial policy at the time, stating "Google does not accept advertising if the ad or site advocates against other individuals, groups, or organizations." The policy was later changed. In June 2008, Google reached an advertising agreement with Yahoo!, which would have allowed Yahoo! to feature Google advertisements on its web pages. The alliance between the two companies was never completely realized because of antitrust concerns by the U.S. Department of Justice. As a result, Google pulled out of the deal in November 2008.
In an attempt to advertise its own products, Google launched a website called Demo Slam, developed to demonstrate technology demos of Google Products.
Search engine  
According to market research published by comScore in November 2009, Google Search is the dominant search engine in the United States market, with a market share of 65.6%. Google indexes billions of web pages, so that users can search for the information they desire through the use of keywords and operators.
In 2003, The New York Times complained about Google's indexing, claiming that Google's caching of content on its site infringed its copyright for the content. In this case, the United States District Court of Nevada ruled in favor of Google in Field v. Google and Parker v. Google. The publication 2600: The Hacker Quarterly has compiled a list of words that the web giant's new instant search feature will not search.
Google Watch has criticized Google's PageRank algorithms, saying that they discriminate against new websites and favor established sites. The site has also alleged that there are connections between Google and the National Security Agency  and the Central Intelligence Agency .
Google also hosts Google Books. The company began scanning books and uploading limited previews, and full books where allowed, into its new book search engine. The Authors Guild, a group that represents 8,000 U.S. authors, filed a class action suit in a New York City federal court against Google in 2005 over this service. Google replied that it is in compliance with all existing and historical applications of copyright laws regarding books. Google eventually reached a revised settlement in 2009 to limit its scans to books from the U.S., the UK, Australia, and Canada. Furthermore, the Paris Civil Court ruled against Google in late 2009, asking it to remove the works of La Martinière  from its database. In competition with Amazon.com, Google sells digital versions of new books.
On July 21, 2010, in response to Bing, Google updated its image search to display a streaming sequence of thumbnails that enlarge when pointed at. Though web searches still appear in a batch per page format, on July 23, 2010, dictionary definitions for certain English words began appearing above the linked results for web searches.
The "Hummingbird" update to the Google search engine was announced in September 2013. The update was introduced over the month prior to the announcement and allows users ask the search engine a question in natural language rather than entering keywords into the search box.
Productivity tools  
Gmail, a free webmail service provided by Google, was launched as an invitation-only beta program on April 1, 2004, The service was upgraded from beta status on July 7, 2009, at which time it had 146 million users monthly. The service was the first online email service with one gigabyte of storage. It was also the first to keep emails from the same conversation together in one thread, similar to an Internet forum. The service offers over 15 GB of free storage, shared with other Google Apps, with additional storage ranging from 20 GB to 16 TB available for $0.25 per 1 GB per year.
Gmail uses AJAX, a programming technique that allows web pages to be interactive without refreshing the browser. Steve Ballmer, Liz Figueroa, Mark Rasch, and the editors of Google Watch have criticised the privacy of Gmail, but Google claims that mail sent to or from Gmail is never read by a human being beyond the account holder and is only used to improve relevance of advertisements.
In 2004, Google started open source software project hosting, called Google Code, which allows developers to download in-development programs at no charge. Google Drive, another part of Google's productivity suite, allows users to create, edit, and collaborate on documents in an online environment, similar to Microsoft Word. The service was originally called Writely, but was obtained by Google on March 9, 2006, and was released as an invitation-only preview. On June 6 after the acquisition, Google created an experimental spreadsheet editing program, which was combined with Google Docs on October 10.
Google for Work is a service from Google that provides customizable enterprise versions of several Google products using a domain name provided by the customer. It features several Web applications with similar functionality to traditional office suites, including Gmail, Hangouts, Google Calendar, Drive, Docs, Sheets, Slides, Groups, News, Play, Sites, and Vault. It was the vision of Rajen Sheth, a Google employee who later developed Chromebooks.
Enterprise products  
Google Search Appliance was launched in February 2002, targeted toward providing search technology for larger organizations.
Google Apps allows organizations to bring Google's web application offerings, Gmail and Google Docs, into their own domains. The service is available in several editions: a basic free edition, Google Apps for Business, Google Apps for Education, and Google Apps for Government. In the same year Google Apps was launched, Google acquired Postini and proceeded to integrate the company's security technologies into Google Apps under the name Google Postini Services.
On March 15, 2016, Google announced the introduction of Google Analytics 360 Suite, "a set of integrated data and marketing analytics products, designed specifically for the needs of enterprise-class marketers." Among other things, the suite is designed to help "enterprise class marketers" see the complete customer journey, generate useful insights, not just more data, and deliver engaging experiences to the right people.
Some see the suite as competing with existing marketing cloud offerings by companies like Adobe, Oracle, Salesforce and IBM.
Other products  
Google Translate is a server-side machine translation service, which can translate between 80 different languages. For some languages, handwriting recognition, or speech recognition can be used as input, and translated text can be pronounced through speech synthesis. The software uses corpus linguistics techniques, where the program "learns" from professionally translated documents, specifically UN and European Parliament proceedings.
Google launched its Google News service in 2002, an automated service which summarizes news articles from various websites. In March 2005, Agence France Presse  sued Google for copyright infringement in federal court in the District of Columbia, a case which Google settled for an undisclosed amount in a pact that included a license of the full text of AFP articles for use on Google News.
Google currently offers free wi-fi access in its hometown of Mountain View, California.
In 2010, Google announced the Google Fiber project, with plans to build an ultra-high-speed broadband network for 50,000 to 500,000 customers in one or more American cities. On March 30, 2011, Google announced that Kansas City, Kansas would be the first community where the new network would be deployed. In July 2012, Google completed the construction of a fiber-optic broadband Internet network infrastructure in Kansas City, and after building an infrastructure, Google announced pricing for Google Fiber. The service will offer three options including a free broadband Internet option, a 1Gbit/s Internet option for $70 per month, and a version that includes television service for $120 per month. The project, called Android, turned out not to be a phone but an operating system for mobile devices, which Google acquired and then released as an open source project under the Apache 2.0 license. Google provides a software development kit for developers so applications can be created to be run on Android-based phones. In September 2008, T-Mobile released the G1, the first Android-based phone. On January 5, 2010, Google released an Android phone under its own company name called the Nexus One. A report in July 2013 stated that Google's share of the global smartphone market, led by Samsung products, was 64% in March 2013.
Other projects Google has worked on include a new collaborative communication service, a web browser, and a mobile operating system. The first of these was first announced on May 27, 2009. The company described Google Wave as a product that helps users communicate and collaborate on the web. The service is Google's "email redesigned", with realtime editing, the ability to embed audio, video, and other media, and extensions that further enhance the communication experience. Google Wave was initially in a developer's preview, where interested users had to be invited to test the service, but was released to the public on May 19, 2010, at Google's I/O keynote. On September 1, 2008, Google pre-announced the upcoming availability of Google Chrome, an open source web browser, which was then released on September 2, 2008. On July 7, 2009, Google announced Google Chrome OS, an open source Linux-based operating system that includes only a web browser and is designed to log users into their Google account.
Google Goggles is a mobile application available on Android and iOS used for image recognition and non-text-based search. In addition to scanning QR codes, the app can recognize historic landmarks, import business cards, and solve Sudoku puzzles. While Goggles could originally identify people as well, Google has limited that functionality as a privacy protection. In late June 2011, Google soft-launched a social networking service called Google+. On July 14, 2011, Google announced that Google+ had reached 10 million users just two weeks after it was launched in this "limited" trial phase. After four weeks in operation, it reached 25 million users.
At a launch event on July 24, 2013, in San Francisco, a newer version of the Nexus 7 Google tablet device was released to the public, alongside the Chromecast dongle that allows users to stream YouTube and Netflix videos via smartphones.
In 2013, Google launched Google Shopping Express, a delivery service initially available only in San Francisco and Silicon Valley.
On February 3, 2014, Google released its first Chromecast SDK.
Google Alerts is a content change detection and notification service, offered by the search engine company Google. The service sends emails to the user when it finds new results—such as web pages, newspaper articles, or blogs—that match the user's search term.
Google Camera is a camera application developed by Google for Android. It is supported on Android 4.4 KitKat and higher versions of Android. It was released on the Google Play Store on April 16, 2014.
Project Fi enables communication across Wi-Fi and cell networks.
In July 2015 Google released DeepDream, an image recognition software capable of creating psychedelic images using a convolutional neural network.
APIs  
Google APIs are a set of application programming interfaces  developed by Google which allow communication with Google Services and their integration to other services. Examples of these include Search, Gmail, Translate or Google Maps. Third-party apps can use these APIs to take advantage of or extend the functionality of the existing services.
Other websites  
Google Developers is Google's site for software development tools, APIs, and technical resources. The site contains documentation on using Google developer tools and APIs—including discussion groups and blogs for developers using Google's developer products.
Google Labs was a page created by Google to demonstrate and test new projects.
Google owns the top-level domain 1e100.net which is used for some servers within Google's network. The name is a reference to the scientific E notation representation for 1 googol, .
Corporate affairs and culture
On Fortune magazine's list of the best companies to work for, Google ranked first in 2007, 2008 and 2012 and fourth in 2009 and 2010. Google was also nominated in 2010 to be the world's most attractive employer to graduating students in the Universum Communications talent attraction index. Google's corporate philosophy includes principles such as "you can make money without doing evil," "you can be serious without a suit," and "work should be challenging and the challenge should be fun."
Employees  
As of 2013, Google had 47,756 employees, among them more than 10,000 software developers based in more than 40 offices.
After the company's IPO in 2004, founders Sergey Brin and Larry Page and CEO Eric Schmidt requested that their base salary be cut to $1. Subsequent offers by the company to increase their salaries were turned down, primarily because their main compensation continues to come from owning stock in Google. Before 2004, Schmidt made $250,000 per year, and Page and Brin each received an annual salary of $150,000.
In 2007 and early 2008, several top executives left Google. In October 2007, former chief financial officer of YouTube Gideon Yu joined Facebook along with Benjamin Ling, a high-ranking engineer. In March 2008, Sheryl Sandberg, then vice-president of global online sales and operations, began her position as chief operating officer of Facebook. At the same time, Ash ElDifrawi, formerly head of brand advertising, left to become chief marketing officer of Netshops.
On April 4, 2011, Larry Page became CEO and Eric Schmidt became Executive Chairman of Google. In July 2012, Google's first female employee, Marissa Mayer, left Google to become Yahoo!'s CEO.
As a motivation technique, Google uses a policy often called Innovation Time Off, where Google engineers are encouraged to spend 20% of their work time on projects that interest them. Some of Google's newer services, such as Gmail, Google News, Orkut, and AdSense originated from these independent endeavors. In a talk at Stanford University, Marissa Mayer, Google's Vice President of Search Products and User Experience until July 2012, showed that half of all new product launches in the second half of 2005 had originated from the Innovation Time Off.
Office locations and headquarters  
Mountain View
Google's headquarters in Mountain View, California, is referred to as "the Googleplex", a play on words on the number googolplex and the headquarters itself being a complex of buildings. The lobby is decorated with a piano, lava lamps, old server clusters, and a projection of search queries on the wall. The hallways are full of exercise balls and bicycles. Many employees have access to the corporate recreation center. Recreational amenities are scattered throughout the campus and include a workout room with weights and rowing machines, locker rooms, washers and dryers, a massage room, assorted video games, table football, a baby grand piano, a billiard table, and ping pong. In addition to the recreation room, there are snack rooms stocked with various foods and drinks, with special emphasis placed on nutrition. Free food is available to employees 24/7, with the offerings provided by paid vending machines prorated based on and favoring those of better nutritional value.
Google's extensive amenities are not available to all of its workers. Temporary workers such as book scanners do not have access to shuttles, Google cafes, or other perks.
New York City
In 2006, Google moved into of office space in New York City, at 111 Eighth Avenue in Manhattan. The office was specially designed and built for Google and houses its largest advertising sales team, which has been instrumental in securing large partnerships. As of February 2012, a significant engineering team is based in New York City. As of September 2013, Google's East Coast office is located at 76 Ninth Ave, New York City, New York.
Other U.S. cities
By late 2006, Google established a new headquarters for its AdWords division in Ann Arbor, Michigan. In November 2006, Google opened offices on Carnegie Mellon's campus in Pittsburgh, focusing on shopping-related advertisement coding and smartphone applications and programs. Other office locations in the U.S. include Atlanta, Georgia; Austin, Texas; Boulder, Colorado; Cambridge, Massachusetts; San Francisco, California; Seattle, Washington; Reston, Virginia, and Washington, D.C.
Google has several international offices.
In October 2006, the company announced plans to install thousands of solar panels to provide up to 1.6 megawatts of electricity, enough to satisfy approximately 30% of the campus' energy needs. The system will be the largest solar power system constructed on a U.S. corporate campus and one of the largest on any corporate site in the world. The idea of trimming lawns using goats originated from Bob Widlar, an engineer who worked for National Semiconductor. In 2008, Google faced accusations in Harper's Magazine of being an "energy glutton". The company was accused of employing its "Don't be evil" motto and its public energy-saving campaigns to cover up or make up for the massive amounts of energy its servers require.
On May 12, 2015, Google announced the setting up of its largest campus outside the United States in Hyderabad, India. The proposed campus can accommodate 6500 employees.
Doodles  
Since 1998, Google has been designing special, temporary alternate logos to place on their homepage intended to celebrate holidays, events, achievements and people. The first Google Doodle was in honor of the Burning Man Festival of 1998. The doodle was designed by Larry Page and Sergey Brin to notify users of their absence in case the servers crashed. Subsequent Google Doodles were designed by an outside contractor, until Larry and Sergey asked then-intern Dennis Hwang to design a logo for Bastille Day in 2000. From that point onward, Doodles have been organized and created by a team of employees termed "Doodlers".
Easter eggs and April Fools' Day jokes  
Google has a tradition of creating April Fools' Day jokes. On April 1, 2000, Google MentalPlex allegedly featured the use of mental power to search the web. In 2007, Google announced a free Internet service called TiSP, or Toilet Internet Service Provider, where one obtained a connection by flushing one end of a fiber-optic cable down their toilet. Also in 2007, Google's Gmail page displayed an announcement for Gmail Paper, allowing users to have email messages printed and shipped to them.
In 2008, Google announced Gmail Custom time where users could change the time that the email was sent.
In 2010, Google changed its company name to Topeka in honor of Topeka, Kansas, whose mayor changed the city's name to Google for a short amount of time in an attempt to sway Google's decision in its new Google Fiber Project. In 2011, Google announced Gmail Motion, an interactive way of controlling Gmail and the computer with body movements via the user's webcam.
Google's services contain easter eggs, such as the Swedish Chef's "Bork bork bork," Pig Latin, "Hacker" or leetspeak, Elmer Fudd, Pirate, and Klingon as language selections for its search engine. The search engine calculator provides the Answer to the Ultimate Question of Life, the Universe, and Everything from Douglas Adams' The Hitchhiker's Guide to the Galaxy. When searching the word "recursion", the spell-checker's result for the properly spelled word is exactly the same word, creating a recursive link.
When searching for the word "anagram," meaning a rearrangement of letters from one word to form other valid words, Google's suggestion feature displays "Did you mean: nag a ram?" In Google Maps, searching for directions between places separated by large bodies of water, such as Los Angeles and Tokyo, results in instructions to "kayak across the Pacific Ocean." During FIFA World Cup 2010, search queries including "World Cup" and "FIFA" caused the "Goooo...gle" page indicator at the bottom of every result page to read "Goooo...al!" instead.
atGoogleTalks  
AtGoogleTalks is a series of presentations by invited speakers sponsored by Google given at various Google offices throughout the world. The series has feature categories such as Authors@Google, Candidates@Google, Women@Google, Musicians@Google and others. For technical topics, there is Google Tech Talks  which is dedicated to exploring areas of technology and science. Guest speakers range from present and past world leaders to little-known poets and artists. Talks range from about 40 to 70 minutes., there had been over 1700 guest speakers.
CodeF  
Google CodeF is a career event and mentoring program organized by Google for female undergraduate computer scientists who have foundational coding skills in at least one of C++, Java or Python. It lasts 12 weeks and consists of eight mentoring meetings held in Google's offices and virtually. The initiative aims to develop female computer scientists and increase the number of women working in the technology industry.
Philanthropy  
In 2004, Google formed the not-for-profit philanthropic Google.org, with a start-up fund of $1 billion. The mission of the organization is to create awareness about climate change, global public health, and global poverty. One of its first projects was to develop a viable plug-in hybrid electric vehicle that can attain 100 miles per gallon. Google hired Larry Brilliant as the program's executive director in 2004, and the current director is Megan Smith.
In 2008, Google announced its "project 10100" which accepted ideas for how to help the community and then allowed Google users to vote on their favorites. After two years of silence, during which many wondered what had happened to the program, Google revealed the winners of the project, giving a total of ten million dollars to various ideas ranging from non-profit organizations that promote education to a website that intends to make all legal documents public and online.
In 2011, Google donated 1 million euros to International Mathematical Olympiad to support the next five annual International Mathematical Olympiads . On July 2012, Google launched a "Legalize Love" campaign in support of gay rights.
Tax avoidance  
Google uses various tax avoidance strategies. Out of the five largest American technology companies, it pays the lowest taxes to the countries of origin of its revenues. The company accomplishes this partly by licensing technology through subsidiaries in Ireland, Bermuda, the Bahamas, and the Netherlands. This has reportedly sparked a French investigation into Google's transfer pricing practices.
Following criticism of the amount of corporate taxes that Google paid in the United Kingdom, Chairman Eric Schmidt said, "It's called capitalism. We are proudly capitalistic." During the same December 2012 interview, Schmidt "confirmed that the company had no intention of paying more to the UK exchequer." In 2013, Schmidt responded to questions about taxes paid in the UK by pointing to the advertising fees Google charged UK companies as a source of economic growth.
Google Vice President Matt Brittin testified to the Public Accounts Committee of the UK House of Commons that his UK sales team made no sales and hence owed no sales taxes to the UK. In January 2016, Google reached a settlement with the UK to pay £130m in back taxes plus higher taxes in future.
Environment  
Since 2007, Google has aimed for carbon neutrality in regard to its operations.
Google disclosed in September 2011 that it "continuously uses enough electricity to power 200,000 homes", almost 260 million watts or about a quarter of the output of a nuclear power plant. Total carbon emissions for 2010 were just under 1.5 million metric tons, most due to fossil fuels that provide electricity for the data centers. Google said that 25 percent of its energy was supplied by renewable fuels in 2010. An average search uses only 0.3 watt-hours of electricity, so all global searches are only 12.5 million watts or 5% of the total electricity consumption by Google.
In June 2013, The Washington Post reported that Google had donated $50,000 to the Competitive Enterprise Institute, a libertarian think tank that calls human carbon emissions a positive factor in the environment and argues that global warming is not a concern.
In July 2013, it was reported that Google had hosted a fundraising event for Oklahoma Senator Jim Inhofe, who has called climate change a "hoax". In 2014 Google cut ties with the American Legislative Exchange Council  after pressure from the Sierra Club, major unions and Google's own scientists because of ALEC's stance on climate change and opposition to renewable energy.
Lobbying  
In 2013, Google ranked 5th in lobbying spending, up from 213th in 2003. In 2012, the company ranked 2nd in campaign donations of technology and Internet sections.
Litigation  
Google has been involved in a number of lawsuits including the High-Tech Employee Antitrust Litigation which resulted in Google being one of four companies to pay a $415 million settlement to employees.

Facebook: history and everything you need to know.

Facebook

Facebook is a corporation and online social networking service headquartered in Menlo Park, California, in the United States. Its website was launched on February 4, 2004, by Mark Zuckerberg with his Harvard College roommates and fellow students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. The founders had initially limited the website's membership to Harvard students, but later expanded it to colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities and later to high-school students. Since 2006, anyone who is at least 13 years old was allowed to become a registered user of the website, though the age requirement may be higher depending on applicable local laws. Its name comes from the face book directories often given to American university students.
After registering to use the site, users can create a user profile, add other users as "friends", exchange messages, post status updates and photos, share videos, use various apps and receive notifications when others update their profiles. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics, and categorize their friends into lists such as "People From Work" or "Close Friends". Also users can complain or block unpleasant people. Facebook had over 1.59 billion monthly active users as of August 2015. Following its Q3 earnings call in 2015, Facebook's market cap soared past $300 billion.
History  
2003–2005: Thefacebook, Thiel investment and name change  
Zuckerberg wrote a program called Facemash on October 28, 2003, while attending Harvard University as a sophomore . According to The Harvard Crimson, the site was comparable to Hot or Not and used "photos compiled from the online facebooks of nine houses, placing two next to each other at a time and asking users to choose the 'hotter' person"
To accomplish this, Zuckerberg hacked into protected areas of Harvard's computer network and copied private dormitory ID images. Harvard did not have a student "Facebook"  at the time, although individual houses had been issuing their own paper facebooks since the mid-1980s, and Harvard's longtime Freshman Yearbook was colloquially referred to as the "Freshman Facebook". Facemash attracted 450 visitors and 22,000 photo-views in its first four hours online.
The site was quickly forwarded to several campus group list-servers, but was shut down a few days later by the Harvard administration. Zuckerberg faced expulsion and was charged by the administration with breach of security, violating copyrights, and violating individual privacy. Ultimately, the charges were dropped. Zuckerberg expanded on this initial project that semester by creating a social study tool ahead of an art history final exam. He uploaded 500 Augustan images to a website, each of which was featured with a corresponding comments section. On February 4, 2004, Zuckerberg launched "Thefacebook", originally located at thefacebook.com.
Six days after the site launched, three Harvard seniors—Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra—accused Zuckerberg of intentionally misleading them into believing he would help them build a social network called HarvardConnection.com. They claimed that he was instead using their ideas to build a competing product. The three complained to The Harvard Crimson and the newspaper began an investigation. They later filed a lawsuit against Zuckerberg, subsequently settling in 2008 for 1.2 million shares .
Membership was initially restricted to students of Harvard College; within the first month, more than half the undergraduates at Harvard were registered on the service. Eduardo Saverin, Dustin Moskovitz, Andrew McCollum, and Chris Hughes joined Zuckerberg to help promote the website. In March 2004, Facebook expanded to the universities of Columbia, Stanford, and Yale. It later opened to all Ivy League colleges, Boston University, New York University, MIT, and gradually most universities in the United States and Canada.
In mid-2004, entrepreneur Sean Parker — an informal advisor to Zuckerberg — became the company's president. In June 2004, Facebook moved its operations base to Palo Alto, California. In 2005, the company dropped "the" from its name after purchasing the domain name facebook.com for US$200,000., the domain facebook.com belonged to AboutFace Corporation before the purchase. this website last appeared on April 8, 2005, whereas from April 10, 2005 to August 4, 2005, this domain gave a 403 error.
In May 2005, Accel partners invested $12.7 million in Facebook, and Jim Breyer added $1 million of his own money. A January 2009 Compete.com study ranked Facebook the most used social networking service by worldwide monthly active users. Entertainment Weekly included the site on its end-of-the-decade "best-of" list saying, "How on earth did we stalk our exes, remember our co-workers' birthdays, bug our friends, and play a rousing game of Scrabulous before Facebook?"
A high-school version of the site was launched in September 2005, which Zuckerberg called the next logical step.  Facebook also expanded membership eligibility to employees of several companies, including Apple Inc. and Microsoft.
2006–2011: public access, Microsoft alliance and rapid growth  
On September 26, 2006, Facebook was opened to everyone at least 13 years old with a valid email address.
In late 2007, Facebook had 100,000 business pages . These started as group pages, but a new concept called company pages was planned. Pages began rolling out for businesses in May 2009.
On October 24, 2007, Microsoft announced that it had purchased a 1.6% share of Facebook for $240 million, giving Facebook a total implied value of around $15 billion. Microsoft's purchase included rights to place international advertisements on the social networking site.
In October 2008, Facebook announced that it would set up its international headquarters in Dublin, Ireland. Almost a year later, in September 2009, Facebook said that it had turned cash-flow positive for the first time.
Traffic to Facebook increased steadily after 2009. The company announced 500 million users in July 2010
In November 2010, based on SecondMarket Inc., Facebook's value was $41 billion. The company had slightly surpassed eBay to become the third largest American web company after Google and Amazon.com.
In early 2011, Facebook announced plans to move its headquarters to the former Sun Microsystems campus in Menlo Park, California. In March 2011, it was reported that Facebook was removing approximately 20,000 profiles offline every day for violations such as spam, graphic content, and underage use, as part of its efforts to boost cyber security.
Release of statistics by DoubleClick showed that Facebook reached one trillion page views in the month of June 2011, making it the most visited website tracked by DoubleClick. According to a Nielsen Media Research study, released in December 2011, Facebook had become the second-most accessed website in the U.S. behind Google.
2012–2013: IPO, lawsuits and one-billionth user  
Facebook eventually filed for an initial public offering on February 1, 2012. Facebook held an initial public offering on May 17, 2012, negotiating a share price of US$38. The company was valued at $104 billion, the largest valuation to date for a newly listed public company.
Facebook Inc. began selling stock to the public and trading on the NASDAQ on May 18, 2012. Based on its 2012 income of $5 billion, Facebook joined the Fortune 500 list for the first time in May 2013, ranked in position 462.
Facebook filed their S1 document with the Securities and Exchange Commission on February 1, 2012. The company applied for a $5 billion IPO, one of the biggest offerings in the history of technology. The IPO raised $16 billion, making it the third-largest in U.S. history.
The shares began trading on May 18; the stock struggled to stay above the IPO price for most of the day, but set a record for the trading volume of an IPO . The first day of trading was marred by technical glitches that prevented orders from going through; only the technical problems and artificial support from underwriters prevented the stock price from falling below the IPO price on the day.
In March 2012, Facebook announced App Center, a store selling applications that operate via the site. The store was to be available on iPhones, Android devices, and mobile web users.
On May 22, 2012, the Yahoo! Finance website reported that Facebook's lead underwriters, Morgan Stanley, JP Morgan, and Goldman Sachs, cut their earnings forecasts for the company in the middle of the IPO process. The stock had begun its freefall by this time, closing at 34.03 on May 21 and 31.00 on May 22. A "circuit breaker" was used in an attempt to slow down the stock price's decline. Securities and Exchange Commission Chairman Mary Schapiro, and Financial Industry Regulatory Authority  Chairman Rick Ketchum, called for a review of the circumstances surrounding the IPO.
Facebook's IPO was consequently investigated, and was compared to a pump and dump scheme. A class-action lawsuit was filed in May 2012 because of the trading glitches, which led to botched orders. Lawsuits were filed, alleging that an underwriter for Morgan Stanley selectively revealed adjusted earnings estimates to preferred clients.
The other underwriters, Facebook's CEO and board, and NASDAQ also faced litigation after numerous lawsuits were filed, while SEC and FINRA both launched investigations. It was believed that adjustments to earnings estimates were communicated to the underwriters by a Facebook financial officer, who used the information to cash out on their positions while leaving the general public with overpriced shares. By the end of May 2012, Facebook's stock lost over a quarter of its starting value, which led the Wall Street Journal to label the IPO a "fiasco".
Zuckerberg announced to the media at the start of October 2012 that Facebook had passed the monthly active users mark of one billion—Facebook defines active users as a logged-in member who visits the site, or accesses it through a third-party site connected to Facebook, at least once a month. Fake accounts were not mentioned in the announcement, but the company continued to remove them after it found that 8.7% of its users were not real in August 2012. The company's data also revealed 600 million mobile users, 140 billion friend connections since the inception of Facebook, and the median age of a user as 22 years.
2013–present: site developments, A4AI and 10th anniversary  
On January 15, 2013, Facebook announced Facebook Graph Search, which provides users with a "precise answer," rather than a link to an answer by leveraging the data present on its site. Facebook emphasized that the feature would be "privacy-aware," returning only results from content already shared with the user.
The company became the subject of a lawsuit by Rembrandt Social Media in February 2013, for patents involving the "Like" button. On April 3, 2013, Facebook unveiled Facebook Home, a user-interface layer for Android devices offering greater integration with the site. HTC announced the HTC First, a smartphone with Home pre-loaded.
On April 15, 2013, Facebook announced an alliance across 19 states with the National Association of Attorneys General, to provide teenagers and parents with information on tools to manage social networking profiles. On April 19, 2013, Facebook officially modified its logo to remove the faint blue line at the bottom of the "F" icon. The letter F moved closer to the edge of the box.
Following a campaign by 100 advocacy groups, Facebook agreed to update its policy on hate speech. The campaign highlighted content promoting domestic and sexual violence against women, and used over 57,000 tweets and more than 4,900 emails that caused withdrawal of advertising from the site by 15 companies, including Nissan UK, House of Burlesque and Nationwide UK. The social media website initially responded by stating that "while it may be vulgar and offensive, distasteful content on its own does not violate our policies". It decided to take action on May 29, 2013, after it "become clear that our systems to identify and remove hate speech have failed to work as effectively as we would like, particularly around issues of gender-based hate."
On June 12, 2013, Facebook announced on its newsroom that it was introducing clickable hashtags to help users follow trending discussions, or search what others are talking about on a topic. A July 2013 Wall Street Journal article identified the Facebook IPO as the cause of a change in the U.S.' national economic statistics, as the local government area of the company's headquarters, San Mateo County, California, became the top wage-earning county in the country after the fourth quarter of 2012. The Bureau of Labor Statistics reported that the average weekly wage in the county was US$3,240, 107% higher than the previous year. It noted the wages were "the equivalent of $168,000 a year, and more than 50% higher than the next-highest county, New York County, at $2,107 a week, or roughly $110,000 a year."
Russian internet firm Mail.Ru sold its Facebook shares for US$525 million on September 5, 2013, following its initial $200 million investment in 2009. Partly owned by Russia's richest man, Alisher Usmanovhe, the firm owned a total of 14.2 million remaining shares prior to the sale. In the same month, the Chinese government announced that it will lift the ban on Facebook in the Shanghai Free Trade Zone "to welcome foreign companies to invest and to let foreigners live and work happily in the free-trade zone." Facebook was first blocked in China in 2009.
Facebook was announced as a member of The Alliance for Affordable Internet  in October 2013, when the A4AI was launched. The A4AI is a coalition of public and private organisations that includes Google, Intel and Microsoft. Led by Sir Tim Berners-Lee, the A4AI seeks to make Internet access more affordable so that access is broadened in the developing world, where only 31% of people are online. Google will help to decrease Internet access prices so that they fall below the UN Broadband Commission's worldwide target of 5% of monthly income.
A Reuters report, published on December 11, 2013, stated that Standard & Poor's announced the placement of Facebook on its S&P 500 index "after the close of trading on December 20." Facebook announced Q4 2013 earnings of $523 million, an increase of $64 million from the previous year, as well as 945 million mobile users.
By January 2014, Facebook's market capitalization had risen to over $134 billion. At the end of January 2014, 1.23 billion users were active on the website every month.
The company celebrated its 10th anniversary during the week of February 3, 2014. In each of the first three months of 2014, over one billion users logged into their Facebook account on a mobile device.
In February 2014, Facebook announced that it would be buying mobile messaging company Whatsapp for US$19 billion in cash and stock. In June 2014, Facebook announced the acquisition of Pryte, a Finnish mobile data-plan firm that aims to make it easier for mobile phone users in underdeveloped parts of the world to use wireless Internet apps.
At the start of July 2014, Facebook announced the acquisition of LiveRail, a San Francisco, California-based online video advertising company. LiveRail's technology facilitates the sale of video inventory across different devices. The terms of the deal were undisclosed, but TechCrunch reported that Facebook paid between US$400 million and $500 million. As part of the company's second quarter results, Facebook announced in late July 2014 that mobile accounted for 62% of its advertising revenue, which is an increase of 21% from the previous year.
Alongside other American technology figures like Jeff Bezos and Tim Cook, Zuckerberg hosted visiting Chinese politician Lu Wei, known as the "Internet czar" for his influence in the enforcement of China's online policy, at Facebook's headquarters on December 8, 2014. The meeting occurred after Zuckerberg participated in a Q&A session at Tsinghua University in Beijing, China, on October 23, 2014, where he attempted to converse in Mandarin—although Facebook is banned in China, Zuckerberg is highly regarded among the people and was at the university to help fuel the nation's burgeoning entrepreneur sector. A book of Chinese president Xi Xinping found on Zuckerberg's office desk attracted a great deal of attention in the media, after the Facebook founder explained to Lu, "I want them  to understand socialism with Chinese characteristics."
Zuckerberg fielded questions during a live Q&A session at the company's headquarters in Menlo Park on December 11, 2014. The question of whether the platform would adopt a dislike button was raised again, and Zuckerberg said, "We're  thinking about it  … It's an interesting question," and said that he likes the idea of Facebook users being able to express a greater variety of emotions. In October 2015, Zuckerberg said that instead of creating a dislike button, Facebook is testing emoji reactions as an alternative to the 'like' button. On February 24, 2016, Facebook launched Facebook Reactions, which allows users to respond to posts with multiple reactions in addition to "liking" it.
As of January 21, 2015, Facebook's algorithm is programmed to filter out false or misleading content, such as fake news stories and hoaxes, and will be supported by users who select the option to flag a story as "purposefully fake or deceitful news." According to Reuters, such content is "being spread like a wildfire" on the social media platform. Facebook maintained that "satirical" content, "intended to be humorous, or content that is clearly labeled as satire," will be taken into account and should not be intercepted. The algorithm, however, has been accused of maintaining a "filter bubble", where both material the user disagrees with and posts with a low level of likes, will also not be seen. In 2015 November, Zuckerberg prolonged period of paternity leave from 4 weeks to 4 months.

Interpublic Group: less than 0.5%
A small group of current and former employees and celebrities own less than 1% each, including Matt Cohler, Jeff Rothschild, Adam D'Angelo, Chris Hughes, and Owen Van Natta, while Reid Hoffman and Mark Pincus have sizable holdings of the company. The remaining 30% or so are owned by employees, an undisclosed number of celebrities, and outside investors. Adam D'Angelo, former chief technology officer and friend of Zuckerberg, resigned in May 2008. Reports claimed that he and Zuckerberg began quarreling, and that he was no longer interested in partial ownership of the company.
Key management personnel consist of: Chris Cox, Sandberg, and Zuckerberg . Mike Vernal is considered to be the company's top engineer., Facebook has over 7,000 employees, and offices in 15 countries. Other managers include chief financial officer David Wehner and public relations head Elliot Schrage.
Facebook was named the 5th best company to work for in 2014 by company-review site Glassdoor as part of its sixth annual Employees' Choice Awards. The website stated that 93% of Facebook employees would recommend the company to a friend.
Revenue  
Most of Facebook's revenue comes from advertising. Facebook generally has a lower clickthrough rate  for advertisements than most major Web sites. According to BusinessWeek.com, banner advertisements on Facebook have generally received one-fifth the number of clicks compared to those on the Web as a whole, although specific comparisons can reveal a much larger disparity. For example, while Google users click on the first advertisement for search results an average of 8% of the time, Facebook's users click on advertisements an average of 0.04% of the time .
Sarah Smith, who was Facebook's Online Sales Operations Manager until 2012, reported that successful advertising campaigns on the site can have clickthrough rates as low as 0.05% to 0.04%, and that CTR for ads tend to fall within two weeks.
The cause of Facebook's low CTR has been attributed to younger users enabling ad blocking software and their adeptness at ignoring advertising messages, as well as the site's primary purpose being social communication rather than content viewing. According to digital consultancy iStrategy Labs in mid-January 2014, three million fewer users aged between 13 and 17 years were present on Facebook's Social Advertising platform compared to 2011. However, Time writer and reporter Christopher Matthews stated in the wake of the iStrategy Labs results:
A big part of Facebook's pitch is that it has so much information about its users that it can more effectively target ads to those who will be responsive to the content. If Facebook can prove that theory to be true, then it may not worry so much about losing its cool cachet.
In December 2014, a report from Frank N. Magid and Associates found that the percentage of teens aged 13 to 17 who used Facebook fell to 88% in 2014, down from 94% in 2013 and 95% in 2012.
Zuckerberg, alongside other Facebook executives, have questioned the data in such reports; although, a former Facebook senior employee has commented: "Mark  is very willing to recognize the strengths in other products and the flaws in Facebook."
On pages for brands and products, however, some companies have reported CTR as high as 6.49% for Wall posts. A study found that, for video advertisements on Facebook, over 40% of users who viewed the videos viewed the entire video, while the industry average was 25% for in-banner video ads.
The company released its own set of revenue data at the end of January 2014 and claimed: Revenues of US$2.59 billion were generated for the three months ending December 31, 2013; earnings per share were 31 cents; revenues of US$7.87 billion were made for the entirety of 2013; and Facebook's annual profit for 2013 was US$1.5 billion. During the same time, independent market research firm eMarketer released data in which Facebook accounted for 5.7 per cent of all global digital ad revenues in 2013 .
Mergers and acquisitions  
On November 15, 2010, Facebook announced it had acquired the domain name fb.com from the American Farm Bureau Federation for an undisclosed amount. On January 11, 2011, the Farm Bureau disclosed $8.5 million in "domain sales income", making the acquisition of FB.com one of the ten highest domain sales in history.
Offices  
In early 2011, Facebook announced plans to move to its new headquarters, the former Sun Microsystems campus in Menlo Park.
All users outside of the US and Canada have a contract with Facebook's Irish subsidiary "Facebook Ireland Limited". This allows Facebook to avoid US taxes for all users in Europe, Asia, Australia, Africa and South America. Facebook is making use of the Double Irish arrangement which allows it to pay just about 2–3% corporation tax on all international revenue.
In 2010, Facebook opened its fourth office, in Hyderabad and the first in Asia.
Facebook, which in 2010 had more than 750 million active users globally including over 23 million in India, announced that its Hyderabad center would house online advertising and developer support teams and provide round-the-clock, multilingual support to the social networking site's users and advertisers globally. With this, Facebook joins other giants like Google, Microsoft, Oracle, Dell, IBM and Computer Associates that have already set up shop. In Hyderabad, it is registered as 'Facebook India Online Services Pvt Ltd'.
Though Facebook did not specify its India investment or hiring figures, it said recruitment had already begun for a director of operations and other key positions at Hyderabad, which would supplement its operations in California, Dublin in Ireland as well as at Austin, Texas.
A custom-built data center with substantially reduced  power consumption compared to existing Facebook data centers opened in April 2011 in Prineville, Oregon. In April 2012, Facebook opened a second data center in Forest City, North Carolina, US. In June 2013, Facebook opened a third data center in LuleÃ¥, Sweden. In November 2014, Facebook opened a fourth data center in Altoona, Iowa, US.
On October 1, 2012, CEO Zuckerberg visited Moscow to stimulate social media innovation in Russia and to boost Facebook's position in the Russian market. Russia's communications minister tweeted that Prime Minister Dmitry Medvedev urged the social media giant's founder to abandon plans to lure away Russian programmers and instead consider opening a research center in Moscow. Facebook has roughly 9 million users in Russia, while domestic analogue VK has around 34 million.
The functioning of a woodwork facility on the Menlo Park campus was announced at the end of August 2013. The facility, opened in June 2013, provides equipment, safety courses and woodwork learning course, while employees are required to purchase materials at the in-house store. A Facebook spokesperson explained that the intention of the facility is to encourage employees to think in an innovative manner because of the different environment, and also serves as an attractive perk for prospective employees.

Open source contributions  
Facebook is both a consumer of and contributor to free and open source software. Facebook's contributions include: HipHop for PHP, Fair scheduler in Apache Hadoop, Apache Hive, Apache Cassandra, and the Open Compute Project.
Facebook also contributes to other opensource projects such as Oracle's MySQL database engine.
Website  
Technical aspects  
The website's primary color is blue as Zuckerberg is red-green colorblind, a realization that occurred after a test undertaken around 2007; he explained in 2010: "blue is the richest color for me—I can see all of blue." Facebook is built in PHP which is compiled with HipHop for PHP, a 'source code transformer' built by Facebook engineers that turns PHP into C++. The deployment of HipHop reportedly reduced average CPU consumption on Facebook servers by 50%.
Facebook is developed as one monolithic application. According to an interview in 2012 with Chuck Rossi, a build engineer at Facebook, Facebook compiles into a 1.5 GB binary blob which is then distributed to the servers using a custom BitTorrent-based release system. Rossi stated that it takes approximately 15 minutes to build and 15 minutes to release to the servers. The build and release process is zero downtime and new changes to Facebook are rolled out daily.
Data is read from these log files using Ptail, an internally built tool to aggregate data from multiple Scribe stores. It tails the log files and pulls data out . Ptail data is separated out into three streams so they can eventually be sent to their own clusters in different data centers . Puma is used to manage periods of high data flow . Data is processed in batches to lessen the number of times needed to read and write under high demand periods . Batches are taken every 1.5 seconds, limited by memory used when creating a hash table.
Facebook uses the Momentum platform from Message Systems to deliver the enormous volume of emails it sends to its users every day.
History  
On July 20, 2008, Facebook introduced "Facebook Beta", a significant redesign of its user interface on selected networks. The Mini-Feed and Wall were consolidated, profiles were separated into tabbed sections, and an effort was made to create a "cleaner" look. After initially giving users a choice to switch, Facebook began migrating all users to the new version starting in September 2008. On December 11, 2008, it was announced that Facebook was testing a simpler signup process.

In 2007, Facebook launched Facebook Pages  to allow "users to interact and affiliate with businesses and organizations in the same way they interact with other Facebook user profiles". On November 6, 2007, more than 100,000 Facebook pages were launched.
In July 2012, Facebook added a same-sex marriage icon to its timeline feature. On February 14, 2014, Facebook expanded the options for user's gender setting, adding a custom input field that allows users to choose from a wide range of gender identities. Users can also set which set of gender-specific pronouns are used in reference to them throughout the site. The change occurs after Nepal's first openly gay politician Sunil Babu Pant sent a letter to Zuckerberg in early 2012 to request the addition of an "Other" gender option for Facebook users; Facebook's official statement on the issue: "People can already opt out of showing their sex on their profile. We're constantly innovating on our products and features and we welcome input from everyone as we explore ways to improve the Facebook experience."
On June 13, 2009, Facebook introduced a "Usernames" feature, whereby pages can be linked with simpler URLs such as  instead of . Many new smartphones offer access to Facebook services through either their Web browsers or applications. An official Facebook application is available for the operating systems Android, iOS, webOS, and Firefox OS. Nokia and Research In Motion both provide Facebook applications for their own mobile devices. As of January 2015, 745 million active users access Facebook through mobile devices every day.
In May 2014, Facebook introduced a feature to allow users to ask for information not disclosed by other users on their profiles. If a user does not provide key information, such as location, hometown, or relationship status, other users can use a new 'ask' button to send a message asking about that item to the user in a single click.
News Feed  
On September 6, 2006, News Feed was announced, which appears on every user's homepage and highlights information including profile changes, upcoming events, and birthdays of the user's friends. This enabled spammers and other users to manipulate these features by creating illegitimate events or posting fake birthdays to attract attention to their profile or cause. Initially, the News Feed caused dissatisfaction among Facebook users; some complained it was too cluttered and full of undesired information, others were concerned that it made it too easy for others to track individual activities .
In response, Zuckerberg issued an apology for the site's failure to include appropriate customizable privacy features. Since then, users have been able to control what types of information are shared automatically with friends. Users are now able to prevent user-set categories of friends from seeing updates about certain types of activities, including profile changes, Wall posts, and newly added friends.
On February 23, 2010, Facebook was granted a patent on certain aspects of its News Feed. The patent covers News Feeds in which links are provided so that one user can participate in the same activity of another user. The patent may encourage Facebook to pursue action against websites that violate its patent, which may potentially include websites such as Twitter.
One of the most popular applications on Facebook is the Photos application, where users can upload albums and photos. Facebook allows users to upload an unlimited number of photos, compared with other image hosting services such as Photobucket and Flickr, which apply limits to the number of photos that a user is allowed to upload. During the first years, Facebook users were limited to 60 photos per album. As of May 2009, this limit has been increased to 200 photos per album.
Privacy settings can be set for individual albums, limiting the groups of users that can see an album. For example, the privacy of an album can be set so that only the user's friends can see the album, while the privacy of another album can be set so that all Facebook users can see it. Another feature of the Photos application is the ability to "tag", or label, users in a photo. For instance, if a photo contains a user's friend, then the user can tag the friend in the photo. This sends a notification to the friend that they have been tagged, and provides them a link to see the photo.
On June 7, 2012, Facebook launched its App Center to its users. It will help the users in finding games and other applications with ease. Since the launch of the App Center, Facebook has seen 150M monthly users with 2.4 times the installation of apps.
The sorting and display of stories in a user's News Feed is governed by the EdgeRank algorithm.
On May 13, 2015 Facebook in association with major news portals launched a program "Instant Articles" to provide rich news experience. Instant articles provides users, access to articles on Facebook news feed without leaving the site.
Like button  
The like button is a social networking feature, allowing users to express their appreciation of content such as status updates, comments, photos, and advertisements. It is also a social plug-in of the Facebook Platform – launched on April 21, 2010 – that enables participating Internet websites to display a similar like button.
Following the termination by the sheriff of Hampton, Virginia, US of employees who liked the Facebook page of an adversary, a federal appeals court in Virginia handed down a decision that the US Constitution protects the rights of US citizens to like any Facebook page of their choosing. US Circuit Judge William Traxler likened the practice to displaying a "political sign in one's front yard." Additionally, in the US the United States Court of Appeals for the Second Circuit upheld a National Labor Relations Board decision which found that one employee's "liking" another employee's negative comments about their employer deserved protection under the National Labor Relations Act, alerting employers to proceed with caution when disciplining employees for Facebook activity.
Following a lengthy period of calls from the public to include a dislike button on the Facebook interface, Zuckerberg explained in a Q&A session on December 11, 2014, that his reticence was due to a concern about a tone of negativity on the platform—whereby users could "shame" others—and he offered the comment option for situations where people were unwilling to use the like function. However, he said, "We're  thinking about it  … It's an interesting question," and said that he likes the idea of Facebook users being able to express a greater variety of emotions. In conjunction, Facebook also introduced a system in February 2012 to verify the identity of certain accounts.
In December 2012, Facebook announced that because of user confusion surrounding its function, the Subscribe button would be re-labeled as a "Follow" buttonmaking it more similar to other social networks with similar functions.
Comparison with Myspace  
The media often compares Facebook to Myspace, but one significant difference between the two Web sites is the level of customization. Another difference is Facebook's requirement that users give their true identity, a demand that MySpace does not make. MySpace allows users to decorate their profiles using HTML and Cascading Style Sheets, while Facebook allows only plain text. Facebook has a number of features with which users may interact. They include the Wall, a space on every user's profile page that allows friends to post messages for the user to see; Pokes, which allows users to send a virtual "poke" to each other ; Photos, that allows users to upload albums and photos; and Status, which allows users to inform their friends of their whereabouts and actions. Facebook also allows users to tag various people in photographs. Depending on privacy settings, anyone who can see a user's profile can also view that user's Wall. In July 2007, Facebook began allowing users to post attachments to the Wall, whereas the Wall was previously limited to textual content only. There is also a difference in the userbase of each site. MySpace, initially, was much more popular with high school students, while Facebook was more popular among college students. A study by the American firm Nielsen Claritas showed that Facebook users are more inclined to use other professional networking sites, such as LinkedIn, than Myspace users. The website is free to its users and generates revenue from advertising, such as banner ads. Facebook requires a user's name and profile picture  to be accessible by everyone. Users can control who sees other information they have shared, as well as who can find them in searches, through their privacy settings.
On November 6, 2007, Facebook launched Facebook Beacon, which was a part of Facebook's advertisement system until it was discontinued in 2009. Its purpose was to allow targeted advertisements and allowing users to share their activities with their friends.
In 2010, Facebook's security team began expanding its efforts to reduce the risks to users' privacy, but privacy concerns remain.
Since 2010, among other social media services, the National Security Agency has been taking publicly posted profile information from users Facebook profiles to discover who they interact with.
On November 29, 2011, Facebook settled Federal Trade Commission charges that it deceived consumers by failing to keep privacy promises.
In August 2013 High-Tech Bridge published a study showing that links included in Facebook messaging service messages were being accessed by Facebook.
In January 2014 two users filed a lawsuit against Facebook alleging that their privacy had been violated by this practice.
Facebook Bug Bounty Program  
On July 29, 2011, Facebook announced its Bug Bounty Program in which security researchers will be paid a minimum of $500 for reporting security holes on Facebook website. Facebook's  page for security researchers says: "If you give us a reasonable time to respond to your report before making any information public and make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service during your research, we will not bring any lawsuit against you or ask law enforcement to investigate you."
Facebook started paying researchers who find and report security bugs by issuing them custom branded "White Hat" debit cards that can be reloaded with funds each time the researchers discover new flaws. "Researchers who find bugs and security improvements are rare, and we value them and have to find ways to reward them," Ryan McGeehan, former manager of Facebook's security response team, told CNET in an interview. "Having this exclusive black card is another way to recognize them. They can show up at a conference and show this card and say 'I did special work for Facebook.'"
India, which has the second largest number of bug hunters in the world, tops the Facebook Bug Bounty Program with the largest number of valid bugs. "Researchers in Russia earned the highest amount per report in 2013, receiving an average of $3,961 for 38 bugs. India contributed the largest number of valid bugs at 136, with an average reward of $1,353. The U.S. reported 92 issues and averaged $2,272 in rewards. Brazil and the UK were third and fourth by volume, with 53 bugs and 40 bugs, respectively, and average rewards of $3,792 and $2,950", Facebook quoted in a post.
Reception  
According to comScore, Facebook is the leading social networking site based on monthly unique visitors, having overtaken main competitor MySpace in April 2008. ComScore reports that Facebook attracted 130 million unique visitors in May 2010, an increase of 8.6 million people. According to third-party web analytics providers, Alexa and SimilarWeb, Facebook is ranked second and first globally respectively, it is the highest-read social network on the Web, with over 20 billion visitors per month, as of 2015. SimilarWeb, Quantcast and Compete.com all rank the website 2nd in the U.S. in traffic. The website is the most popular for uploading photos, with 50 billion uploaded cumulatively. In 2010, Sophos's "Security Threat Report 2010" polled over 500 firms, 60% of which responded that they believed that Facebook was the social network that posed the biggest threat to security, well ahead of MySpace, Twitter, and LinkedIn. the United Kingdom, and the United States. However, Facebook still receives limited adoption in countries such as Japan, where domestically created social networks are still largely preferred. In regional Internet markets, Facebook penetration is highest in North America, followed by Middle East-Africa, Latin America, Europe, and Asia-Pacific . Some of the top competitors were listed in 2007 by Mashable.
The website has won awards such as placement into the "Top 100 Classic Websites" by PC Magazine in 2007, and winning the "People's Voice Award" from the Webby Awards in 2008. In a 2006 study conducted by Student Monitor, a company specializing in research concerning the college student market, Facebook was named the second most popular thing among undergraduates, tied with beer and only ranked lower than the iPod.
In 2010, Facebook won the Crunchie "Best Overall Startup Or Product" for the third year in a row and was recognized as one of the "Hottest Silicon Valley Companies" by Lead411. However, in a July 2010 survey performed by the American Customer Satisfaction Index, Facebook received a score of 64 out of 100, placing it in the bottom 5% of all private-sector companies in terms of customer satisfaction, alongside industries such as the IRS e-file system, airlines, and cable companies. The reasons why Facebook scored so poorly include privacy problems, frequent changes to the website's interface, the results returned by the News Feed, and spam.
In December 2008, the Supreme Court of the Australian Capital Territory ruled that Facebook is a valid protocol to serve court notices to defendants. It is believed to be the world's first legal judgement that defines a summons posted on Facebook as legally binding. In March 2009, the New Zealand High Court associate justice David Gendall allowed for the serving of legal papers on Craig Axe by the company Axe Market Garden via Facebook. Employers have also used Facebook as a means to keep tabs on their employees and have even been known to fire them over posts they have made.
By 2005, the use of Facebook had already become so ubiquitous that the generic verb "facebooking" had come into use to describe the process of browsing others' profiles or updating one's own. In 2008, Collins English Dictionary declared "Facebook" as its new Word of the Year. In December 2009, the New Oxford American Dictionary declared its word of the year to be the verb "unfriend", defined as "To remove someone as a 'friend' on a social networking site such as Facebook.
In early 2010, Openbook was established, an avowed parody  website that enables text-based searches of those Wall posts that are available to "Everyone", i.e. to everyone on the Internet.
Writers for The Wall Street Journal found in 2010 that Facebook apps were transmitting identifying information to "dozens of advertising and Internet tracking companies". The apps used an HTTP referer which exposed the user's identity and sometimes their friends'. Facebook said, "We have taken immediate action to disable all applications that violate our terms".
In May 2014, the countries with the most Facebook users were:
United States with 151.8 million members
India with 108.9 million members
Brazil with 70.5 million members
Indonesia with 60.3 million members
Mexico with 44.4 million members
Facebook's popularity throughout the world  has led to some countries and employers blocking access to the site.
All of the above total 309 million members or about 38.6 percent of Facebook's 1 billion worldwide members. As of March 2013, Facebook reported having 1.11 billion monthly active users, globally.
In regards to Facebook's mobile usage, per an analyst report in early 2013, there are 192 million Android users, 147 million iPhone users, 48 million iPad users and 56 million messenger users, and a total of 604 million mobile Facebook users. In January 2016, Facebook Messenger hits 800 million users.

Criticisms and controversies  
Electricity usage  
On April 21, 2011, Greenpeace released a report showing that of the top ten big brands in cloud computing, Facebook was most reliant on coal for electricity for its data centers. At the time, data centers consumed up to 2% of all global electricity and this amount was projected to increase. Phil Radford of Greenpeace said "we are concerned that this new explosion in electricity use could lock us into old, polluting energy sources instead of the clean energy available today." On December 15, 2011, Greenpeace and Facebook announced together that Facebook would shift to use clean and renewable energy to power its own operations. Marcy Scott Lynn, of Facebook's sustainability program, said it looked forward "to a day when our primary energy sources are clean and renewable" and that the company is "working with Greenpeace and others to help bring that day closer."
Google  
In May 2011 emails were sent to journalists and bloggers making critical allegations about Google's privacy policies; however it was later discovered that PR giant Burson-Marsteller was paid for the emails by Facebook .
Users violating minimum age requirements  
A 2011 study in the online journal First Monday, examines how parents consistently enable children as young as 10 years old to sign up for accounts, directly violating Facebook's policy banning young visitors. This policy is in compliance with a United States law, the 1998 Children's Online Privacy Protection Act, which requires minors aged 13 or younger to gain explicit parental consent to access commercial websites. In other jurisdictions where a similar law sets a lower minimum age, Facebook enforces the lower age. Of the 1,007 households surveyed for the study, 76% of parents reported that their child joined Facebook when they were younger than 13, the minimum age in the site's terms of service. The study also reported that Facebook removes roughly 20,000 users each day for violating its minimum age policy. The study's authors also note, "Indeed, Facebook takes various measures both to restrict access to children and delete their accounts if they join." The findings of the study raise questions primarily about the shortcomings of United States federal law, but also implicitly continue to raise questions about whether or not Facebook does enough to publicize its terms of service with respect to minors. Only 53% of parents said they were aware that Facebook has a minimum signup age; 35% of these parents believe that the minimum age is merely a recommendation, or thought the signup age was 16 or 18, and not 13.
Accounts hacked in Bangalore, India  
In November 2011, several Facebook users in Bangalore, India reported that their accounts had been hacked and their profile pictures replaced with pornographic images. For more than a week, users' news feeds were spammed with pornographic, violent and sexual content, and it was reported that more than 200,000 accounts were affected. Facebook described the reports as inaccurate, and Bangalore police speculated that the stories may have been rumors spread by Facebook's competitors.
Unauthorized wall posting bug  
On August 19, 2013, it was reported that a Facebook user from Yatta, West Bank Khalil Shreateh had found a bug that allowed him to post material to other users' Facebook Walls. Users are not supposed to have the ability to post material to the Facebook Walls of other users unless they are approved friends of those users that they have posted material to. To prove that he was telling the truth, Shreateh posted material to Sarah Goodin's wall, a friend of Facebook CEO Mark Zuckerberg. Following this, Shreateh contacted Facebook's security team with the proof that his bug was real, explaining in detail what was going on. Facebook has a bounty program in which it compensates people a US$500 fee for reporting bugs instead of using them to their advantage or selling them on the black market. However, it was reported that instead of fixing the bug and paying Shreateh the fee, Facebook originally told him that "this was not a bug" and dismissed him. Shreateh then tried a second time to inform Facebook, but they dismissed him yet again. On the third try, Shreateh used the bug to post a message to Mark Zuckerberg's Wall, stating "Sorry for breaking your privacy … but a couple of days ago, I found a serious Facebook exploit" and that Facebook's security team was not taking him seriously. Within minutes, a security engineer contacted Shreateh, questioned him on how he performed the move and ultimately acknowledged that it was a bug in the system. Facebook temporarily suspended Shreateh's account and fixed the bug after several days. Facebook refused to pay out the bounty to Shreateh, stating that by posting to Zuckerberg's account, Shreateh had violated one of their terms of service policies and therefore "could not be paid." Facebook also noted that in Shreateh's initial reports, he had failed to provide technical details for Facebook to act on the bug.
On August 22, 2013, Yahoo News reported that Marc Maiffret, a chief technology officer of the cybersecurity firm BeyondTrust, is prompting hackers to support in raising a $10,000 reward for Khalil Shreateh. On August 20, Maiffret stated that he had already raised $9,000 in his efforts, including the $2,000 he himself contributed. He and other hackers alike have denounced Facebook for refusing Shreateh compensation. Stated Maiffret, "He is sitting there in Palestine doing this research on a five-year-old laptop that looks like it is half broken. It's something that might help him out in a big way." Facebook representatives have since responded, "We will not change our practice of refusing to pay rewards to researchers who have tested vulnerabilities against real users." Facebook representatives also claimed they'd paid out over $1 million to individuals who have discovered bugs in the past.
Users quitting  
A 2013 study examined the reasons users eventually quit the site. It found the most common reasons were privacy concerns, general dissatisfaction with Facebook, negative aspects regarding Facebook friends  and the feeling of getting addicted to Facebook . Facebook quitters were found to be more concerned about privacy, more addicted to the Internet and more conscientious.
Lane v. Facebook, Inc.  
On March 2010, Judge Richard Seeborg issued an order approving the class settlement in Lane v. Facebook, Inc. This lawsuit charged that user's private information was being posted on Facebook without consent using Facebook's Beacon program.
User influence experiments  
Academic and Facebook researchers have collaborated to test if the messages people see on Facebook can influence their behavior. For instance, in "A 61-Million-Person Experiment in Social Influence And Political Mobilization," during the 2010 elections, Facebook users were given the opportunity to "tell your friends you voted" by clicking on an "I voted" button. Users were 2% more likely to click the button if it was associated with friends who had already voted.
Much more controversially, a 2014 study of "Emotional Contagion Through Social Networks" manipulated the balance of positive and negative messages seen by 689,000 Facebook users. The researchers concluded that they had found "some of the first experimental evidence to support the controversial claims that emotions can spread throughout a network,  the effect sizes from the manipulations are small."
Unlike the "I voted" study, which had presumptively beneficial ends and raised few concerns, this study was criticized for both its ethics and methods/claims. As controversy about the study grew, Adam Kramer, a lead author of both studies and member of the Facebook data team, defended the work in a . A few days later, Sheryl Sandburg, Facebook's COO, made a statement while traveling abroad. While at an Indian Chambers of Commerce event in New Delhi she stated that "This was part of ongoing research companies do to test different products, and that was what it was. It was poorly communicated and for that communication we apologize. We never meant to upset you."
Shortly thereafter, on July 3, 2014, USA Today reported that the privacy watchdog group Electronic Privacy Information Center  had filed a formal complaint with the Federal Trade claiming that Facebook had broken the law when it conducted the study on the emotions of its users without their knowledge or consent. In its complaint, EPIC alleged that Facebook had deceived it users by secretly conducting a psychological experiment on their emotions: "At the time of the experiment, Facebook did not state in the Data Use Policy that user data would be used for research purposes. Facebook also failed to inform users that their personal information would be shared with researchers."
Beyond the ethical concerns, other scholars criticized the methods and reporting of the study's findings. John Grohol, writing at PsycCentral, argued that despite its title and claims of "emotional contagion," this study did not look at emotions at all. Instead, its authors used an application  that simply counted positive and negative words in order to infer users' sentiments. He wrote that a shortcoming of the LIWC tool is that it does not understand negations. Hence, the tweet "I am not happy" would be scored as positive: "Since the LIWC 2007 ignores these subtle realities of informal human communication, so do the researchers." Grohol concluded that given these subtleties, the effect size of the findings are little more than a "statistical blip."
Kramer et al.  found a 0.07% — that's not 7 percent, that's 1/15th of one percent!! — decrease in negative words in people's status updates when the number of negative posts on their Facebook news feed decreased. Do you know how many words you'd have to read or write before you've written one less negative word due to this effect? Probably thousands.
The consequences of the controversy are pending  but it did prompt an "" from its publisher, the Proceedings of the National Academy of Sciences, as well as an blog posting from OkCupid that "!" In September 2014, law professor James Grimmelmann argued that the actions of both companies were "illegal, immoral, and mood-altering" and filed notices with the Maryland Attorney General and Cornell Institutional Review Board.
In the UK, the study was also criticised by the British Psychological Society which said, in a letter to The Guardian, "There has undoubtedly been some degree of harm caused, with many individuals affected by increased levels of negative emotion, with consequent potential economic costs, increase in possible mental health problems and burden on health services. The so-called 'positive' manipulation is also potentially harmful."
Real-name policy controversy and compromise  
Facebook has a real-name system policy for user profiles. The real-name policy stems from the position "that way, you always know who you're connecting with. This helps keep our community safe." Facebook's real-name system does not allow adopted names or pseudonyms, and in its enforcement has suspended accounts of legitimate users, until the user provides identification indicating the name. Facebook representatives have described these incidents as very rare. A user claimed responsibility via the anonymous Android and iOS app Secret for reporting "fake names" which caused user profiles to be suspended, specifically targeting the stage names of drag queens. On October 1, 2014, Chris Cox, Chief Product Officer at Facebook, offered an apology: "In the two weeks since the real-name policy issues surfaced, we've had the chance to hear from many of you in these communities and understand the policy more clearly as you experience it. We've also come to understand how painful this has been. We owe you a better service and a better experience using Facebook, and we're going to fix the way this policy gets handled so everyone affected here can go back to using Facebook as you were."
On December 15, 2015, Facebook announced in a press release that it would be providing a compromise to its real name policy after protests from groups such as the gay/lesbian community and abuse-victims. The site is developing a protocol that will allow members to provide specifics as to their "special circumstance" or "unique situation" with a request to use pseudonyms, subject to verification of their true identities. At that time, this was already being tested in the U.S. Product manager Todd Gage and vice president of global operations Justin Osofsky also promised a new method for reducing the number of members who must go through ID verification while ensuring the safety of others on Facebook. The fake name reporting procedure will also be modified, forcing anyone who makes such an allegation to provide specifics that would be investigated and giving the accused individual time to dispute the allegation.
"Free basics" controversy in India  
In February 2016, TRAI ruled against differential data pricing for limited services from mobile phone operators effectively ending zero-rating platforms in India. Zero rating provides access to limited number of websites for no charge to the end user. Net-neutrality supporters from India brought out the negative implications of Facebook Free Basic program and spread awareness to the public. Facebook’s Free Basics program was a collaboration with Reliance Communications to launch Free Basics in India. The TRAI ruling against differential pricing marked the end of Free Basics in India.
Earlier, Facebook had spent $44 million USD in advertising and it implored all of its Indian users to send an email to the Telecom Regulatory Authority to support its program. TRAI later asked Facebook to provide specific responses from the supporters of Free Basics
Safety Check bug  
On March 27, 2016, following a bombing in Lahore, Pakistan, Facebook activated its "Safety Check" feature, which allows people to let friends and loved ones know they are okay following a crisis or natural disaster, to people who were never in danger, or even close to the Pakistan explosion. Some users as far as the US, UK and Egypt received notifications asking if they were okay.
Impact  
Media impact  
In April 2011, Facebook launched a new portal for marketers and creative agencies to help them develop brand promotions on Facebook. The company began its push by inviting a select group of British advertising leaders to meet Facebook's top executives at an "influencers' summit" in February 2010. Facebook has now been involved in campaigns for True Blood, American Idol, and Top Gear. News and media outlets such as the Washington Post, Financial Times and ABC News have used aggregated Facebook fan data to create various infographics and charts to accompany their articles. In 2012, the beauty pageant Miss Sri Lanka Online was run exclusively using Facebook.
Social impact  
Facebook has affected the social life and activity of people in various ways. Facebook allows people using computers or mobile phones to continuously stay in touch with friends, relatives and other acquaintances wherever they are in the world, as long as there is access to the Internet. It has reunited lost family members and friends. It allows users to trade ideas, stay informed with local or global developments, and unite people with common interests and/or beliefs through groups and other pages.
Facebook's social impact has also changed how people communicate. Rather than having to reply to others through email, Facebook allows users to broadcast or share content to others, and thereby to engage others or be engaged with others' posts.
Facebook has been successful and more socially impactful than many other social media sites. David Kirkpatrick, technology journalist and author of The Facebook Effect, believes that Facebook is structured in a way that is not easily replaceable. He challenges users to consider how difficult it would be to move all the relationships and photos to an alternative. Facebook has let people participate in an atmosphere with the "over the backyard fence quality" of a small town, despite the move to larger cities.
Emotional health impact  
Recent studies have shown that Facebook causes negative effects on self-esteem by triggering feelings of envy, with vacation and holiday photos proving to be the largest resentment triggers. Other prevalent causes of envy include posts by friends about family happiness and images of physical beauty—such envious feelings leave people lonely and dissatisfied with their own lives. A joint study by two German universities discovered that one out of three people were more dissatisfied with their lives after visiting Facebook, and another study by Utah Valley University found that college students felt worse about their own lives following an increase in the amount of time spent on Facebook.
According to professor of psychology Susan Krauss Whitbourne, although Facebook has an upside of friending people, there is also the downside of having someone unfriend or reject another person. Whitbourne refers to unfriended persons on Facebook as victims of estrangement. In August 2010, one of North Korea's official government websites and the official news agency of the country, Uriminzokkiri, joined Facebook.
During the Arab Spring many journalists made claims that Facebook played a major role in generating the 2011 Egyptian revolution. On January 14, the Facebook page of "We are all khaled Said" was started by Wael Ghoniem Create Event to invite the Egyptian people to "peaceful demonstrations" on January 25. According to Mashable, in Tunisia and Egpyt, Facebook became the primary tool for connecting all protesters and led the Egyptian government of Prime Minister Nazif to ban Facebook, Twitter and another websites on January 26 then ban all mobile and Internet connections for all of Egypt at midnight January 28. After 18 days, the uprising forced President Mubarak to resign.
In Bahrain uprising which started on February 14, 2011, Facebook was utilized by the Bahraini regime as well as regime loyalists to identify, capture and prosecute citizens involved in the protests. A 20-year-old girl named Ayat Al Qurmezi was identified as a protester using Facebook, taken from her home by masked commandos and put in prison.
In 2011, Facebook filed paperwork with the Federal Election Commission to form a political action committee under the name FB PAC. In an email to The Hill, a spokesman for Facebook said "Facebook Political Action Committee will give our employees a way to make their voice heard in the political process by supporting candidates who share our goals of promoting the value of innovation to our economy while giving people the power to share and make the world more open and connected."
During the Syrian civil war, the YPG, a libertarian army for Rojava has recruited westerners through Facebook in its fight against ISIL. Dozens have joined its ranks for various reasons from religious to ideological. The Facebook page's name "The Lions of Rojava" comes from a Kurdish saying which translates as "A lion is a lion, whether it's a female or a male", reflecting the organisation's feminist ideology.
United States    
Facebook's role in the American political process was demonstrated in January 2008, shortly before the New Hampshire primary, when Facebook teamed up with ABC and Saint Anselm College to allow users to give live feedback about the "back to back" January 5 Republican and Democratic debates. Facebook users took part in debate groups organized around specific topics, register to vote, and message questions.
Over a million people installed the Facebook application "US Politics on Facebook" in order to take part, and the application measured users' responses to specific comments made by the debating candidates. This debate showed the broader community what many young students had already experienced: Facebook as a popular and powerful new way to interact and voice opinions. A poll by CBS News, UWIRE and The Chronicle of Higher Education claimed to illustrate how the "Facebook effect" has affected youth voting rates, support by youth of political candidates, and general involvement by the youth population in the 2008 election.
The new social media, such as Facebook and Twitter, made use first of the personal computer and the Internet, and after 2010 of the smart phones to connect hundreds of millions of people, especially those under age 35. By 2008, politicians and interest groups were experimenting with systematic use of social media to spread their message among much larger audiences than they had previously reached.
Facebook is having an impact on local government as well. Justin Smith, a Colorado sheriff uses Facebook to disseminate his ideas on matters relating to local, state, and national concerns. He also publicizes crimes, particularly those that his department solves. He has seven thousand followers on the social medium, considered a large number. Smith said that he rarely goes out in public "when I don't get feedback from folks. … Facebook is an interesting tool because I think it holds candidates and elected officials more accountable. Voters know where someone stands."
As American political strategists turn their attention to the 2016 presidential contest, they identify Facebook as an increasingly important advertising tool. Recent technical innovations have made possible more advanced divisions and subdivisions of the electorate. Most important, Facebook can now deliver video ads to small, highly targeted subsets. Television, by contrast, shows the same commercials to all viewers, and so cannot be precisely tailored.
Ban  
In many countries the social networking sites and mobile apps have been blocked temporarily or permanently. In Bangladesh, the government has been blocking Facebook, WhatsApp, Tango, Viber and many other sites and apps since November 18, 2015.
In popular culture  
American author Ben Mezrich published a book in July 2009 about Zuckerberg and the founding of Facebook, titled The Accidental Billionaires: The Founding of Facebook, A Tale of Sex, Money, Genius, and Betrayal.
The Social Network, a drama film directed by David Fincher and adapted from Mezrich's book, was released October 1, 2010. People portrayed in the movie, including Zuckerberg, have criticized its accuracy. However a search of IMDB will reveal this to be a movie produced as standard entertainment.
In response to the Everybody Draw Mohammed Day controversy and the banning of the website in Pakistan, an Islamic version of the website was created, called MillatFacebook.
"You Have 0 Friends", an April 2010 episode of the American animated comedy series, South Park, explicitly parodied Facebook.
At age 102, Ivy Bean of Bradford, England joined Facebook in 2008, making her one of the oldest people ever on Facebook. At the time of her death in July 2010, she had 4,962 friends on Facebook and more than 56,000 followers on Twitter.
On May 16, 2011, an Israeli couple named their daughter after the Facebook "like" feature.
In July 2014, Shakira became the first celebrity to cross over 100 million likes, Cristiano Ronaldo is the second to reach 100 million likes, ahead of Rihanna and Eminem, who had 98 million and 89 million likes respectively. Mark Zuckerberg posted a congratulatory message on the artist's wall.
