When Did Facebook Start?

Facebook was founded on February 4, 2004 in Cambridge, Massachusetts. It was started by Mark Zuckerberg while he studied psychology at Harvard University at the age of 19.

As a programmer, Zuckerberg had previous experience with several online projects before launching Facebook. The site was original called "The Facebook," and the company changed its name to Facebook in August 2005 after purchasing the domain name for $200,000. After its initial launch at Harvard University, the social site spread to other American universities before allowing high school students to sign up on September 2005. A week after Zuckerberg launched Facebook, three seniors at Harvard claimed that he stole the idea from them. As of June 2014, Facebook claims that the site has 1.32 billion active users.
