I can't edit above so I will add it here: * '09 spent $400 on $700M of revenue ($300M profit) * profitable since Q2 of 09 * one of the only social networks to ever reach profitability * 55% of US retailers present on Facebook * 20% of global social network ad revenues * 550,000 approved apps, 1M developers * 20% of users have logged into another site using connect * Zynga revenue is over $40M a month. Up to $10M of that goes to Facebook for advertising, while Facebook then take 30% of what Zynga make through Facebook revenue. So Zynga first pay Facebook to get the users, then pay Facebook again when they make money from those users.
