Facebook's History: From Dorm To IPO Darling

Facebook proved an instant hit at Harvard and soon expanded to more universities across the United States and Canada. In 2005 it expanded to high schools and employees of select companies, including Apple and Microsoft. The following year the site opened its doors to everyone at least 13, and Facebook as we know it today was born. The social network had 12 million users by December 2006.
