Facebook is likely to generate $2bn revenue in 2010, a figure that surpasses earlier estimates, Bloomberg reported on Thursday quoting sources.
Sales are likely to more than double from 2009, the sources added. The social networking site had $700m to $800m in sales last year and the 2010 figure was previously expected to be closer to $1.5bn.
The site's primary source of income is from advertisements and virtual currencies. Among internet companies, Facebook could be the fastest in reaching the $2bn mark.
While Google finds out users preferences by analysing users' search characteristics, Facebook users reveal their preferences in their personal profiles. This advantage is expected to give the social networking site an edge over other companies in targeting the right groups for its advertisers.
