Facebook recently revealed that their sales in 2011 were $3.7 billion with profits of $1 billion as part of their 2011 IPO. Zynga, notably accounted for 12 percent of sales in 2011, around $445 million, primarily from virtual goods sales and advertising and is a notable risk should Zynga decide to divest itself of the mobile network.

“If the use of Zynga games on our platform declines, if Zynga launches games on or migrates games to competing platforms, or if we fail to maintain good relations with Zynga, we may lose Zynga as a significant Platform developer and our financial results may be adversely affected,” stated Facebook.
