Facebook (formerly [thefacebook]) is an online social networking service headquartered in Menlo Park, California. Its website was launched on February 4, 2004, by Mark Zuckerberg with his college roommates and fellow Harvard University students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes.[7] 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. Facebook now allows anyone who claims to be at least 13 years old to become a registered user of the website.[8] Its name comes from a colloquialism for the directory given to it by American universities students.[9]
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 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". Facebook had over 1.3 billion active users as of June 2014.[2] Due to the large volume of data collected about users, the service's privacy policies have faced scrutiny, among other criticisms. Facebook, Inc. held its initial public offering in February 2012 and began selling stock to the public three months later, reaching a peak market capitalization of $104 billion.

"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"[13][14]
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" (a directory with photos and basic information) at the time, although individual houses had been issuing their own paper facebooks since the mid-1980s. Facemash attracted 450 visitors and 22,000 photo-views in its first four hours online.[13][15]

Facebook was founded by Mark Zuckerberg with his college roommates and fellow students Eduardo Saverin, Dustin Moskovitz and Chris Hughes.[6] The website's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities before opening to high school students, and eventually to anyone aged 13 and over. However, according to a May 2011 Consumer Reports survey, there are 7.5 million children under 13 with accounts and 5 million under 10, violating the site's terms of service.[7]
A January 2009 Compete.com study ranked Facebook as the most used social networking service by worldwide monthly active users.[8] 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?"[9] Critics, such as Facebook Detox,[10] state that Facebook has turned into a national obsession that results in vast amounts of time lost and innately encourages narcissism. Quantcast estimates Facebook has 138.9 million monthly unique U.S. visitors in May 2011.[11] According to Social Media Today, in April 2010 an estimated 41.6% of the U.S. population had a Facebook account.[12] Nevertheless, Facebook's market growth started to stall in some regions, with the site losing 7 million active users in the United States and Canada in May 2011.[13] Facebook purchased fb.com on January 11, 2011 for 8.5 million dollars making the acquisition of FB.com one of the ten highest domain sales in history. Again in 2012 it bought the photo sharing website Instagram for 1 billion dollars.

Comparison with Myspace
The media often compares Facebook to MySpace, but one significant difference between the two Web sites is the level of customization.[68] Another difference is Facebook's requirement that users give their true identity, a demand that MySpace does not make.[69] MySpace allows users to decorate their profiles using HTML and Cascading Style Sheets (CSS), while Facebook allows only plain text.[70] 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;[71] Pokes, which allows users to send a virtual "poke" to each other (a notification then tells a user that they have been poked);[72] Photos, where users can upload albums and photos;[73] and Status, which allows users to inform their friends of their whereabouts and actions.[74] 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.[71]

Since April 2011 Facebook users have had the ability to make live voice calls via Facebook Chat, allowing users to chat with others from all over the world. This feature, which is provided free through T-Mobile's new Bobsled service, lets the user add voice to the current Facebook Chat as well as leave voice messages on Facebook.[98]

Facebook has affected the social life and activity of people in various ways. With its availability on many mobile devices, Facebook allows users 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 can also unite people with common interests and/or beliefs through groups and other pages, and has been known to reunite lost family members and friends because of the widespread reach of its network. One such reunion was between John Watson and the daughter he had been seeking for 20 years. They met after Watson found her Facebook profile.[164] Another father-daughter reunion was between Tony Macnauton and Frances Simpson, who had not seen each other for nearly 48 years.[165]

Main articles: History of Facebook and Timeline of Facebook
Mark Zuckerberg wrote Facemash, the predecessor to Facebook, on October 28, 2003, while attending Harvard 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".[16][17]
To accomplish this, Zuckerberg hacked into the protected areas of Harvard's computer network and copied the houses' private dormitory ID images. Harvard at that time did not have a student "facebook" (a directory with photos and basic information), though individual houses had been issuing their own paper facebooks since the mid-1980s. Facemash attracted 450 visitors and 22,000 photo-views in its first four hours online.[16][18]
The site was quickly forwarded to several campus group list-servers, but was shut down a few days later by the Harvard administration. Zuckerberg was charged by the administration with breach of security, violating copyrights, and violating individual privacy, and faced expulsion. Ultimately, the charges were dropped.[19] Zuckerberg expanded on this initial project that semester by creating a social study tool ahead of an art history final, by uploading 500 Augustan images to a website, with one image per page along with a comment section.[18] He opened the site up to his classmates, and people started sharing their notes.
The following semester, Zuckerberg began writing code for a new website in January 2004. He was inspired, he said, by an editorial in The Harvard Crimson about the Facemash incident.[20] On February 4, 2004, Zuckerberg launched "Thefacebook", originally located at thefacebook.com.[21]
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, while he was instead using their ideas to build a competing product.[22] The three complained to the Harvard Crimson, and the newspaper began an investigation. The three later filed a lawsuit against Zuckerberg, subsequently settling.[23]
Membership was initially restricted to students of Harvard College, and within the first month, more than half the undergraduate population at Harvard was registered on the service.[24] Eduardo Saverin (business aspects), Dustin Moskovitz (programmer), Andrew McCollum (graphic artist), and Chris Hughes soon joined Zuckerberg to help promote the website. In March 2004, Facebook expanded to Stanford, Columbia, and Yale.[25] It soon opened to the other Ivy League schools, Boston University, New York University, MIT, and gradually most universities in Canada and the United States.[26][27]

To accomplish this, Zuckerberg hacked into the protected areas of Harvard's computer network and copied the houses' private dormitory ID images. Harvard at that time did not have a student "facebook" (a directory with photos and basic information). Facemash attracted 450 visitors and 22,000 photo-views in its first four hours online.[14][16]
The site was quickly forwarded to several campus group list-servers, but was shut down a few days later by the Harvard administration. Zuckerberg was charged by the administration with breach of security, violating copyrights, and violating individual privacy, and faced expulsion. Ultimately, however, the charges were dropped.[17] Zuckerberg expanded on this initial project that semester by creating a social study tool ahead of an art history final, by uploading 500 Augustan images to a Web site, with one image per page along with a comment section.[16] He opened the site up to his classmates, and people started sharing their notes.

The following semester, Zuckerberg began writing code for a new Web site in January 2004. He was inspired, he said, by an editorial in The Harvard Crimson about the Facemash incident.[18] On February 4, 2004, Zuckerberg launched "Thefacebook", originally located at thefacebook.com.[19]
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, while he was instead using their ideas to build a competing product.[20] The three complained to the Harvard Crimson, and the newspaper began an investigation. The three later filed a lawsuit against Zuckerberg, subsequently settling.[21]
Membership was initially restricted to students of Harvard College, and within the first month, more than half the undergraduate population at Harvard was registered on the service.[22] Eduardo Saverin (business aspects), Dustin Moskovitz (programmer), Andrew McCollum (graphic artist), and Chris Hughes soon joined Zuckerberg to help promote the Web site. In March 2004, Facebook expanded to Stanford, Columbia, and Yale.[23] It soon opened to the other Ivy League schools, Boston University, New York University, MIT, and gradually most universities in Canada and the United States.[24][25]

Most of Facebook's revenue comes from advertising. Microsoft is Facebook's exclusive partner for serving banner advertising,[57] and therefore Facebook serves only advertisements that exist in Microsoft's advertisement inventory.
