Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and entrepreneur. As a Harvard College student he founded the online social networking service 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. Zuckerberg launched Facebook from his Harvard dorm room on February 4, 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 30 schools. Zuckerberg moved to Palo Alto, California with Moskovitz and some friends during the summer of 2004. They leased a small house which served as their first office. Over the summer, Zuckerberg met Peter Thiel who invested in the company. Today, the company has four buildings in downtown Palo Alto.
