Zynga accounted for 12% of Facebook sales in 2011
Social network files for $5bn IPO
Facebook has filed for its initial public offering, seeking to raise $5 billion in funding.
According to the company's IPO, sales during 2011 were $3.7 billion with profits of $1 billion.
The company also revealed that social gaming company Zynga accounted for 12 per cent of sales in 2011, around $445 million, primarily from virtual goods sales and advertising. The company is so important to Facebook that it lists it as a significant risk for the business should Zynga launch games with competitors.
"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 the company.
Data purely for the month of December shows that the social network has a total of 825 million users, and 425 million users accessed the site through mobile devices.
