Mark Zuckerberg, Eduaro Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes founded Facebook in 2003 as a social networking website for Harvard students called Facemash which later became Thefacebook.com and then Facebook.com. Over time Facebook expanded to include organizations, individuals, video chatting, business tools, and grew to become one of the largest and most popular social media platforms worldwide despite ongoing concerns about privacy and the amount of time users spend on the site.
