Abstract
Facebook is a social networking service launched in February 2004 that is operated and privately owned by Facebook, Inc. As of now the social networking site has over 500 million active users across the globe. Users can create a personal profile, add other users as friends and exchange messages, including automatic notifications when they update their profile. Moreover, users can join common interest user groups, organized by city, workplace, school, college or other characteristics.
Mark Zuckerberg, while attending Harvard as a sophomore, launched the Facebook in February 2004. Membership was initially restricted to students of Harvard University. In two weeks after its launch, the social networking site was a huge hit; half of the student body at Harvard had signed up. Other schools in the Boston area began demanding a Facebook network. Zuckerberg immediately recruited his friends Dustin Moskowitz and Chris Hughes to help build Facebook, and within four months, Facebook added 30 more college networks.
