Mark Elliot Zuckerberg (born May 14, 1984) is an American computer programmer and Internet entrepreneur. He is a co-founder of Facebook, and currently operates as its chairman and chief executive officer. His net worth is estimated to be US $73.1 billion as of January 2018, making him the fifth richest person in the world.
Zuckerberg launched Facebook from his Harvard University dormitory room on February 4, 2004 with college roommates and fellow Harvard students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. The group then introduced Facebook to other college campuses. It published its own student directory, “The Photo Address Book”, which students referred to as “The Facebook”. Such photo directories were an important part of the student social experience at many private schools. With them, students were able to list attributes such as their class years, their friends, and their telephone numbers.
Facebook expanded rapidly, reaching one billion users by 2012. During this time, Zuckerberg became involved in various legal disputes brought by his friends and cofounders, who claimed they were due to a share of the company based upon their involvement during its development phase.
Once at college, Zuckerberg’s Facebook started off as just a “Harvard thing” until Zuckerberg decided to spread it to other schools, enlisting the help of roommate Dustin Moskovitz. They began with Columbia University, New York University, Stanford, Dartmouth, Cornell, University of Pennsylvania, Brown, and Yale. Samyr Laine, a triple jumper representing Haiti at the 2012 Summer Olympics, shared a room with Zuckerberg during Facebook’s founding. “Mark was clearly on to great things,” said Laine, who was Facebook’s fourteenth user.
Since 2010, Time magazine has named Zuckerberg among the 100 wealthiest and most influential people in the world as a part of its Person of the Year award. In December 2016, Zuckerberg was ranked 10th on Forbes list of The World’s Most Powerful People.
