Farmville Creator Zynga Valued at $10B

Earlier this month we wrote about the Facebook valuation and its component factors.  One of the revenue contributors was Credits on Games and Applications, adding an estimated 16.8% to the revenues of Facebook.  Well, it was only a matter of time before the big money (Morgan Stanley, Fidelity, etc.), followed that trail, and now virtual-game Farmville creator Zynga is getting up to $500M in funding based on a valuation of $10B (it's their second $500M round). ( puts Zynga's venture-backed investment value at just over $6B.)

Kara Swisher reports Zynga annual revenues could hit $1B. Here’s how they make money.
