I know Performics was part of the DoubleClick acquisition, but has Google ever sold any part of the company before?

* blogoscoped.com/archive/2008-0 ... :

<< Google plans to sell of[f] the DoubleClick’s search engine marketing unit Performics, as it brings with it a conflict of interest for Google’s neutrality. >>

A search engine company running an SEO side business isn't exactly the best type of business to be in. Everyone would cry foul if Google didn't sell Performics.

Some more info on Performics according to Wikipedia:
