Very interesting, and could be a real winner, if implemented correctly.
Could This Be The First Appearance Of a Facebook Ad Network

Zynga’s off-Facebook games platform Zynga.com now displays Facebook ads and Sponsored Stories, as part of what could be the beginnings of a Facebook ad network across the web. According to the Facebook Help Center, “When you connect with Facebook on Zynga.com, you’ll see personalized ads and sponsored stories. The Facebook ads you see on Zynga are the same ads you see on Facebook.com.” Those ads appear in the sidebar, which is where we’ve previously seen Zynga serve ads via Google AdSense.

UPDATED
The quoted story above was updated later with:

Facebook provided the following statement, “We have had a close relationship with Zynga for a number of years and we think we can deliver value to Zynga and to the people playing their games by showing the same ads that they see on Facebook. We will not be showing ads on other sites at this time.”
