Facebook is a social networking service
and website launched in February 2004, owned and operated by Facebook,
Inc. As of May 2012,
Facebook has over 900
million active users, more than half of them using Facebook on a mobile
device. 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". The name of the service stems from the colloquial name for the book
given to students at the start of the academic year by some university
administrations in the United States to help students get to know each other.
Facebook allows any users who declare themselves to be at least 13 years old to
become registered users of the site.
Facebook was founded by Mark Zuckerberg with his college
roommates and fellow students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. 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 eventually to anyone aged 13 and over. However, according to a May 2011 Consumer Reports survey, there are
7.5 million children under 13 with accounts and 5 million under 10, violating
the site's terms of service.
A January 2009 Compete.com study ranked
Facebook as the most used social networking service by worldwide monthly active
users. Entertainment Weekly included the site 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?" Critics, such as Facebook Detox, state that Facebook
has turned into a national obsession that results in vast amounts of time lost
and innately encourages narcissism. Quantcast estimates Facebook
has 138.9 million monthly unique U.S. visitors in May 2011. According to Social
Media Today, in April 2010 an estimated 41.6% of the U.S. population had a
Facebook account. Nevertheless, Facebook's market growth started to stall in
some regions, with the site losing 7 million active users in the United States
and Canada in May 2011. Facebook purchased fb.com on January 11, 2011 for 8.5
million dollars making the acquisition of FB.com one of the ten highest domain
sales in history. Again in 2012 it bought the photo sharing website Instagram
for 1 billion dollars.
