Yes, that is technically correct. Technically, because in practice zynga is dead without facebook: http://arstechnica.com/gaming/news/2011/07/zyngas-ipo-filing-details-risk-dependence-on-facebook.ars http://arstechnica.com/gaming/news/2011/07/zyngas-ipo-filing... Let me explain a bit more: no other social network has the combination of virality (some call it spam), reach and suitable audience (non-geeks, and non-teens) that facebook offers. With the current roster of games, zynga can only be successful on facebook. Sure, if facebook shuts down their channels, zynga will move to orkut, or hi5 or some chinese social network. BUT, over there zynga will make 1/10 of the revenues, basically because they are popular in non-lucrative markets. OTOH, Zynga has signed an agreement with facebook, in which, i presume facebook has agreed not to cut off the viral channels for a number of years.
