Mark Elliot Zuckerberg, (born May 14, 1984) is an American computer programmer and entrepreneur. A Harvard dropout, he is credited with developing and launching the online social networking website Facebook with the help of fellow Harvard student and computer science major Andrew McCollum as well as roommates Dustin Moskovitz and Chris Hughes. He now serves as Facebook's CEO. In 2008, Forbes Magazine declared him " youngest billionaire on earth and possibly the youngest self-made billionaire ever", with an estimated net worth of $1.5 billion USD. However, the validity of this label has also been met with controversy.
Zuckerberg launched Facebook from his Harvard dorm room on February 15, 2004. It quickly became a success at Harvard and more than two-thirds of the school's students signed up in the first two weeks. Zuckerberg then decided to spread Facebook to other schools and enlisted the help of roommate Dustin Moskovitz. They first spread it to Stanford, Columbia and Yale and then to other Ivy League colleges and schools in the Boston area. By the beginning of the summer, Zuckerberg and Moskovitz had released Facebook at almost forty five schools.
