The founders had initially limited the website's membership to Harvard students; however, later they expanded it to higher education institutions in the Boston area, the Ivy League schools, and Stanford University. Facebook gradually added support for students at various other universities, and eventually to high school students as well. Since 2006, anyone age 13 and older has been allowed to become a registered user of Facebook, though variations exist in the minimum age requirement, depending on applicable local laws.[10] The Facebook name comes from the face book directories often given to United States university students.[11]
Facebook can be accessed by a large range of desktops, laptops, tablet computers ,and smartphones over the Internet and mobile networks. After registering to use the site, users can create a user profile indicating their name, occupation, schools attended and so on. Users can add other users as "friends", exchange messages, post status updates and digital photos, share digital videos and links, use various software applications ("apps"), and receive notifications when others update their profiles or make posts. Additionally, users may join common-interest user groups organized by workplace, school, hobbies or other topics, and categorize their friends into lists such as "People From Work" or "Close Friends". In groups, editors can pin posts to top. Additionally, users can complain about or block unpleasant people. Because of the large volume of data that users submit to the service, Facebook has come under scrutiny for its privacy policies. Facebook makes most of its revenue from advertisements which appear onscreen.
Facebook, Inc. held its initial public offering (IPO) in February 2012, and began selling stock to the public three months later, reaching an original peak market capitalization of $104 billion. On July 13, 2015, Facebook became the fastest company in the Standard & Poor's 500 Index to reach a market cap of $250 billion.[12] Facebook has more than 1.65 billion monthly active users as of March 31, 2016.[13] As of April 2016, Facebook was the most popular social networking site in the world, based on the number of active user accounts.[14]

Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University, California. 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 (IPO) took place on August 19, 2004, and Google moved to its new headquarters in Mountain View, California, nicknamed the Googleplex.[10]
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.[11][12][13][14][15]
Rapid growth since incorporation has triggered a chain of products, acquisitions and partnerships beyond Google's core search engine (Google Search). It offers online productivity software (Google Docs) including email (Gmail), a cloud storage service (Google Drive) and a social networking service (Google+). Desktop products include applications for web browsing (Google Chrome), organizing and editing photos (Google Photos), and instant messaging and video chat (Hangouts). The company leads the development of the Android mobile operating system and the browser-only Chrome OS[16] for a class of netbooks known as Chromebooks and desktop PCs known as Chromeboxes. Google has moved increasingly into communications hardware, partnering with major electronics manufacturers[17] in the production of its "high-quality low-cost"[18] Nexus devices.[19] In 2012, a fiber-optic infrastructure was installed in Kansas City to facilitate a Google Fiber broadband service.[20]
Google has been estimated to run more than one million servers in data centers around the world (as of 2007).[21] It processes over one billion search requests[22] and about 24 petabytes of user-generated data each day (as of 2009).[23][24][25][26] 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.[27]
Google's 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".[28][29][30] In October 2015, the motto was replaced in the Alphabet corporate code of conduct by the phrase: "Do the right thing".[31] Google's commitment to such robust idealism has been increasingly been called into doubt due to a number of actions and behaviours which appear to contradict this.[32][33]

It is globally known for its Web portal, search engine Yahoo! Search, and related services, including Yahoo! Directory, Yahoo! Mail, Yahoo! News, Yahoo! Finance, Yahoo! Groups, Yahoo! Answers, advertising, online mapping, video sharing, fantasy sports, and its social media website. It is one of the most popular sites in the United States.[12] According to third-party web analytics providers, Alexa and SimilarWeb, Yahoo! is the highest-read news and media website, with over 7 billion views per month, being the fourth most visited website globally, as of June 2015.[7][13][14] According to news sources, roughly 700 million people visit Yahoo websites every month.[15][16] Yahoo itself claims it attracts "more than half a billion consumers every month in more than 30 languages".[17]
Once the most popular website in the U.S., Yahoo started to slowly decline since the late 2000s,[18] and on July 25, 2016 Verizon Communications announced its intent to acquire Yahoo's internet business for US$4.8 billion—the company was once worth over US$100 billion.[19][20][21] Its 15% stake in Alibaba Group and 35.5% stake in Yahoo! Japan will remain intact.[22]
