Zynga generated 12% of Facebook's 2011 revenue
In the course of filing a $5 billion IPO, Facebook has revealed just how important Zynga is to the social network's success.
Zynga generated $445 million in revenue for Facebook over 2011, 12% of its total for the year, according to documents released today.
Most of Facebook's other revenue comes from advertising; in total, the company brought in $3.71 billion in 2011, with a profit of $1 billion.
Facebook has made a market valuation of $100 billion as part of its first IPO filing, although this figure is likely to undergo revision as the big day approaches, and has saved up $4 billion in ready funds. No date has been set for the IPO beyond later this year.
Comparing their IPOs, Zynga netted a record-breaking $1 billion (the largest tech IPO since Google's $1.67 billion in 2004), which is 20% of Facebook's expected $5 billion.
