In February 2004, Zuckerberg and his Harvard University roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes developed the Facebook social networking service from their dorm room. Initially limited to a few college campuses, the site quickly grew in popularity and finally surpassed one billion users by 2012. In May 2012, Zuckerberg took the firm public with a controlling stake. He became the world's youngest self-made billionaire at the age of 23 in 2007. Zuckerberg's net worth is $122 billion as of October 2021,[4] making him the world's fifth richest person. [4]
Since 2008, Time magazine has ranked Zuckerberg one of the top 100 most influential people in the world.
