FaceMash, Facebook's predecessor, opened in 2003, developed by Mark Zuckerberg; he wrote the software for the Facemash website when he was in his second year of college. The website was set up as a type of "hot or not" game for Harvard students.
The website allowed visitors to compare two female student pictures side by side and let them decide who was more attractive.
Chris Hughes, says when his roommate Mark Zuckerberg came up with the idea, it was to be “a directory of information for college students”.
Just six days after the launch of the site, three Harvard University seniors accused Zuckerberg of intentionally misleading them into believing that he would help them build a social network called HarvardConnection.com but instead using their idea to build a competing product.
On Dec 11, 2005, universities in Australia and New Zealand were added to the Facebook network, bringing its size to 2.000+ colleges and 25.000+ high schools throughout the United States, Canada, Mexico, the United Kingdom, Australia, New Zealand, and Ireland.
