Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and Internet entrepreneur. He is best known as one of five co-founders of the social networking site Facebook. Zuckerberg is the chairman and chief executive of Facebook, Inc. Zuckerberg’s personal wealth is estimated to be $9.4 billion as of 2012.
Born and raised in New York state, Zuckerberg began writing software as a hobby in middle school, with help from his father and a tutor (who called him a prodigy). In high school, he excelled in classic literature and fencing while studying at Phillips Exeter Academy.
Zuckerberg later attended Harvard College, majoring in computer science and psychology. In his sophomore year, he wrote a notorious application that he called Facemash that allowed students on the college’s network to vote on the relative attractiveness of other students. It was shut down within days, and led to disciplinary action.
Together with his college roommates and fellow Harvard University students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes they launched Facebook from their dormitory room. They took Facebook to other campuses nationwide and soon after moved to Palo Alto, California. By 2007, Facebook had made him a billionaire at the age of 23. By 2010, Facebook had an estimated 500 million users worldwide and reached 1 billion in 2012. Zuckerberg was involved in various legal disputes initiated by others who claimed a share of the company due to their help in setting it up.
Since 2010, Zuckerberg has been named among the 100 wealthiest and most influential people in the world by Time magazine’s Person of the Year. In 2010 the founding of Facebook was made into a major Hollywood movie, The Social Network where he was portrayed by Jesse Eisenberg.
