Facebook (stylized facebook) is a social network service and website launched in February
2004 that is operated and privately owned by Facebook, Inc.[1] As of January 2011, Facebook has
more than 600 million active users.[5][6] Users 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. The name of the service stems from the colloquial name for the
book given to students at the start of the academic year by university administrations in the US
with the intention of helping students to get to know each other better. Facebook allows anyone
who declares themselves to be at least 13 years old to become a registered user of the website.

Facebook was founded by Mark Zuckerberg with his college roommates and fellow computer
science students Eduardo Saverin, Dustin Moskovitz and Chris Hughes.[7] The website's
membership was initially limited by the founders to Harvard students, but was expanded to other
colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support
for students at various other universities before opening to high school students, and, finally, to
anyone aged 13 and over.

A January 2009 Compete.com study ranked Facebook as the most used social network service by
worldwide monthly active users, followed by MySpace.[8] Entertainment Weekly put it on its end-
of-the-decade "best-of" list, saying, "How on earth did we stalk our exes, remember our co-
workers' birthdays, bug our friends, and play a rousing game of Scrabulous before Facebook?"[9]
Quantcast estimates Facebook has 135.1 million monthly unique U.S. visitors in October 2010.

According to Social Media Today as of April 2010, it is estimated that 41.6% of the U.S.
population has a Facebook account.[11]
