Facebook is a social networking service launched in
February 2004, owned and operated by Facebook, Inc.[5] As of September
2012, Facebook has over one billion active users,[6] more than half of
whom use Facebook on a mobile device.[7] Users must register before
using the site, after which they may create a personal profile, add
other users as friends, and exchange messages, including automatic
notifications when they update their profile. Additionally, users may
join common-interest user groups, organized by workplace, school or
college, or other characteristics, and categorize their friends into
lists such as "People From Work" or "Close Friends".
