Facebook, Inc. is an American online social media and social networking service company. It is based in Menlo Park, California. Its was founded by Mark Zuckerberg, along with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. It is considered one of the Big Four technology companies along with Amazon, Apple, and Google.[8][9]

The founders initially limited the website's membership to Harvard students and subsequently Columbia, Stanford, and Yale students. Membership was eventually expanded to the remaining Ivy League schools, MIT, and higher education institutions in the Boston area. Facebook gradually added support for students at various other universities, and eventually to high school students. Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered user of Facebook, though variations exist in this requirement, depending on local laws. The name comes from the face book directories often given to American university students. Facebook held its initial public offering (IPO) in February 2012, valuing the company at $104 billion, the largest valuation to date for a newly listed public company. It began selling stock to the public three months later. Facebook makes most of its revenue from advertisements that appear onscreen.

The Facebook service can be accessed from devices with Internet connectivity, such as personal computers, tablets and smartphones. After registering, users can create a customized profile revealing information about themselves. Users can post text, photos and multimedia of their own devising and share it with other users as "friends". Users can use various embedded apps, and receive notifications of their friends' activities. Users may join common-interest groups.

Facebook had more than 2.2 billion monthly active users as of January 2018. It receives prominent media coverage, including many controversies such as user privacy[10][11] and psychological effects. The company has faced intense pressure over censorship and over content that some users find objectionable.

Facebook's initial public offering (IPO) in February 2012 was the largest initial valuation to date for a public company ($104 billion).

Facebook offers other products and services. It acquired Instagram, WhatsApp and Oculus Rift and independently developed Facebook Messenger.


2003–2006: Thefacebook, Thiel investment, and name change

Zuckerberg built a website called "Facemash" in 2003 while attending Harvard University. 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".[12] Facemash attracted 450 visitors and 22,000 photo-views in its first four hours.[13] The site was sent to several campus group list-servers, but was shut down a few days later by Harvard administration. Zuckerberg faced expulsion and was charged with breaching security, violating copyrights and violating individual privacy. Ultimately, the charges were dropped.[12] Zuckerberg expanded on this project that semester by creating a social study tool ahead of an art history final exam. He uploaded all art images to a website, each of which was accompanied by a comments section, then shared the site with his classmates.[14]

Original layout and name of Thefacebook, 2004

A "face book" is a student directory featuring photos and personal information.[13] In 2003, Harvard had only a paper version[15] along with private online directories.[12][16] Zuckerberg told the Crimson, "Everyone's been talking a lot about a universal face book within Harvard. ... I think it's kind of silly that it would take the University a couple of years to get around to it. I can do it better than they can, and I can do it in a week."[16] In January 2004, Zuckerberg coding a new website, known as "TheFacebook", inspired by a Crimson editorial about Facemash, stating, "It is clear that the technology needed to create a centralized Website is readily available ... the benefits are many." Zuckerberg met with Harvard student Eduardo Saverin, and each of them agreed to invest $1,000 in the site.[17] On February 4, 2004, Zuckerberg launched "TheFacebook", originally located at thefacebook.com.[18]

Six days after the site launched, Harvard seniors Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra accused Zuckerberg of intentionally misleading them into believing that 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.[19] The three complained to the Crimson and the newspaper began an investigation. They later sued Zuckerberg, settling in 2008[20] for 1.2 million shares (worth $300 million at Facebook's IPO).[21]

Membership was initially restricted to students of Harvard College. Within a month, more than half the undergraduates had registered.[22] Dustin Moskovitz, Andrew McCollum, and Chris Hughes joined Zuckerberg to help manage the growth of the website.[23] In March 2004, Facebook expanded to Columbia, Stanford and Yale.[24] and then to all Ivy League colleges, Boston University, New York University, MIT, Washington and successively most universities in the United States and Canada.[25][26]

In mid-2004, Napster co-founder and entrepreneur Sean Parker—an informal advisor to Zuckerberg—became company president.[27] In June 2004, the company moved to Palo Alto, California.[28] It received its first investment later that month from PayPal co-founder Peter Thiel.[29] In 2005, the company dropped "the" from its name after purchasing the domain name facebook.com for US$200,000.[30] The domain had belonged to AboutFace Corporation.

In May 2005, Accel Partners invested $12.7 million in Facebook, and Jim Breyer[31] added $1 million of his own money. A high-school version of the site launched in September 2005.[32] Eligibility expanded to include employees of several companies, including Apple Inc. and Microsoft.[33]

A company representative called the milestone a "quiet revolution."[45] In November 2010, based on SecondMarket Inc. (an exchange for privately held companies' shares), 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.[46][47]

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.[48]

In February 2011, Facebook announced plans to move its headquarters to the former Sun Microsystems campus in Menlo Park, California.[49][50] In March 2011, it was reported that Facebook was removing about 20,000 profiles daily for violations such as spam, graphic content and underage use, as part of its efforts to boost cyber security.[51] Statistics showed that Facebook reached one trillion page views in the month of June 2011, making it the most visited website tracked by DoubleClick.[52][53] According to a Nielsen study, Facebook had in 2011 become the second-most accessed website in the U.S. behind Google.[54][55]

The letter F moved closer to the edge of the box.[77]

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 led 15 advertisers to withdrawal, including Nissan UK, House of Burlesque and Nationwide UK.
