Facebook, the giant social networking site, has emerged as a major news player. In 2010, all but one of the top websites for which referral data was available got at least some of their traffic from Facebook. The only exception was Google News, which includes connections to other websites in their content.
Facebook has a global audience of around 500 million users, far larger than any single news outlet. Its function has shifted from that of a social network allowing friends to share personal information to that of a platform for individuals to share, recommend, and link all types of information, including news.
If looking for news was the most significant development of the previous decade, sharing news could be one of the most significant developments of the next.
Marketers have been using Facebook's immense reach and popularity to promote their products and businesses to their target demographic.
