Facebook is a social networking service originally launched as Facemash in 2003. It became TheFacebook on February 4, 2004, before changing its name to simply Facebook in August 2005.[1] Facebook was rebranded to Meta on October 28, 2021 during the Connect 2021.[2]
TheFacebook's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League,[4] and gradually most universities in the United States and Canada,[5][6] corporations,[7] and by September 2006 - since 2005 under the name Facebook - to everyone with a valid email address along with an age requirement of being 13 or older.[8][9]
