Facebook is a social networking service and website launched in February 2004, operated and privately owned by Facebook Inc. As of February 2012, Facebook has more than 845 million active users. Users must register before using the site, after which they may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. 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". The name of the service stems from the colloquial name for the book given to students at the start of the academic year by some university administrations in the United States to help students get to know each other. Facebook allows any users who declare themselves to be at least 13 years old to become registered users of the site.
Facebook was founded by Mark Zuckerberg with his college roommates and fellow students Eduardo Saverin, Dustin Moskovitz and Chris Hughes. The Web site'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, based on ConsumersReports.org in May 2011, there are 7.5 million children under 13 with accounts and 5 million under 10, violating the site's terms of service.
A January 2009 Compete.com study ranked Facebook as 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?" Quantcast estimates Facebook has 138.9 million monthly unique U.S. visitors in May 2011. According to Social Media Today, in April 2010 an estimated 41.6% of the U.S. population had a Facebook account. 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. Facebook filed for an initial public offering on February 1, 2012.
Mark Elliot Zuckerberg |
Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and Internet entrepreneur. He is best known for co-creating the social networking site Facebook, of which he is chief executive. It was co-founded as a private company in 2004 by Zuckerberg and classmates Dustin Moskovitz, Eduardo Saverin, and Chris Hughes while they were students at Harvard University. In 2010, Zuckerberg was named Time magazine's Person of the Year. As of 2011, his personal wealth was estimated to be $17.5 billion making him one of the world's youngest billionaires.
Zuckerberg was born in 1984 in White Plains, New York to Karen, a psychiatrist, and Edward Zuckerberg, a dentist. He and his three sisters, Randi, Donna, and Arielle,were brought up in Dobbs Ferry, New York. Zuckerberg was raised Jewish and had his bar mitzvah when he turned 13; he has since described himself as an atheist.
At Ardsley High School, Zuckerberg had excelled in the classics before transferring to Phillips Exeter Academy in his junior year, where he won prizes in science (math, astronomy and physics) and classical studies (on his college application, Zuckerberg listed as non-English languages he could read and write: French, Hebrew, Latin, and ancient Greek) and was a fencing star and captain of the fencing team.In college, he was known for reciting lines from epic poems such as The Iliad.
At a party put on by his fraternity during his sophomore year, Zuckerberg met Priscilla Chan, a Chinese-American fellow student originally from the Boston suburbs,and they began dating in 2003. In September 2010, Zuckerberg invited Chan, by then a medical student at the University of California, San Francisco, to move into his rented Palo Alto house. Zuckerberg studied Mandarin Chinese in preparation for the couple's visit to China in December 2010.
On Zuckerberg's Facebook page, he listed his personal interests as "openness, making things that help people connect and share what's important to them, revolutions, information flow, minimalism".Zuckerberg sees blue best because of red–green colorblindness; blue is also Facebook's dominant color.
