Facebook’s revenue in 2009 was nearly $800 million and the company turned a part of it into a solid net profit, according to Reuters, who cites two sources familiar with the situation. The number is significantly higher than earlier 2009 estimates of $500 million, and even the projected $710 million of revenue in 2010. Facebook, as usual, declines to comment on any of these numbers, but we know that it became cash-flow positive in 2009.
