Zynga Names Google in Updated Investor List

Social game developer Zynga yesterday filed a 619-page document with the SEC, triple the length of its original IPO filing and filled with new, previously undisclosed information, according to AllThingsD’s Tricia Duryee.

The new document includes a long list of Zynga’s investors—the first of which is Google. The search giant’s name was left out of Zynga’s first SEC filing, and was likely included in the new amended document after the SEC made comments about it, according to Duryee. This is the first time Zynga has officially disclosed that Google is an investor.

Last year, TechCrunch reported that Google had made a secret investment of $100 million. Since then, Duryee says, AllThingsD has heard that the investment may have been even bigger, and could have something to do with the launch of a new social games network in Google+.

The amount of capital raised hasn’t changed in the new filing. In the updated document, Zynga said it still raised three official rounds between February 2008 and February 2011, adding up to $845 million. The biggest round, $490 million, was raised as recently as this past February.
