Mark Zuckerberg was born in 1984 in New York. He began programming at a young age and attended Harvard University, where he created Facemash and a predecessor to Facebook. After moving to California, he launched Facebook from his dorm room in 2004. Facebook grew rapidly and by 2010 had over 500 million users worldwide, making Zuckerberg one of the youngest billionaires ever. He has since been involved in several legal disputes regarding Facebook's creation and profits.
