I read this yesterday:

http://techcrunch.com/2010/03/02/google-chris-henger/

Behavior-based marketing solutions provider Catalina Marketing ... has tapped former Google exec Chris Henger to run its Digital Services business unit.
... Henger served as a member of the executive team at Performics ... which was acquired by DoubleClick in 2004, for six years. After the acquisition, Henger played a key role in integrating DoubleClick Performics with Google’s Affiliate Network launch.
Seems like a fairly big loss for GAN.
