Facebook probably needs no introduction; nonetheless, here is a quick history of the company.
The world’s biggest and most-famous social network was launched by Mark Zuckerberg while he was a student at Harvard University, in early 2004. TheFacebook, as it was then known, was originally intended to serve a digitised version of the ‘face books’ held by Harvard’s various colleges, which were paper directories containing images and personal information about students.
Initially limited to Harvard, Facebook expanded to include students at other elite US universities, before branching out to all universities and high schools in the US and Canada. In 2006, it was finally decided to open the site up to the general public.
