Facebook is an American for-profit corporation an an onwab social media an social networkin service based in Menlo Park, Californie. The Facebook wabsteid wis lencht on Februar 4, 2004, bi Mark Zuckerberg, alang wi fallae Harvard College students an roommates, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, an Chris Hughes.[6][7]

The foonders haed ineetially leemitit the wabsteid's membership tae Harvard students; houiver, later thay expandit it tae heicher eddication institutions in the Boston aurie, the Ivy League schuils, an Stanford Varsity. Facebook gradually addit support for students at various ither varsities, an eventually tae heich schuil students as well. Syne 2006, onyane wha claims tae be at least 13 year auld haes been alloued tae acome a registered uiser o Facebook, tho variations exeest in the meenimum age requirement, dependin on applicable local laws.[8] The Facebook name comes frae the face beuk directories eften gien tae Unitit States varsity students.[9]
