Facebook was founded by Mark Zuckerberg with his college roommates and fellow computer science students Eduardo Saverin, Dustin Moskovitz and Chris Hughes.The website's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and Stanford University. It later expanded further to include (potentially) any university student, then high school students, and, finally, to anyone aged 13 and over.
Facebook has met with some controversy. It has been blocked intermittently in several countries including Pakistan, Syria, China, Vietnam,, and Iran. It has also been banned at many places of work to discourage employees from wasting time using the service. Privacy has also been an issue, and it has been compromised several times. Facebook settled a lawsuit regarding claims over source code and intellectual property. The site has also been involved in controversy over the sale of fans and friends
