Mark Zuckerberg founded Facebook with his college roommates and fellow
computer science students Eduardo Saverin, Dustin Moskovitz and Chris Hughes while
he was a student at Harvard University.
The website’s membership was initially limited to Harvard students, but it later
expanded further to include any university student. In late 2005, it was open to high
school students, and finally, in 2006, Facebook became available to anyone aged 13
and over with a valid e-mail address.
Facebook was once only available through a computer, however; in 2006
applications became available that make Facebook available through mobile phones,
PDAs, iPods and other mp3 devices. There are more than 65 million active
users currently accessing Facebook through their mobile devices.
