From ITWorld - “The complaint by The Center for Digital Democracy (CDD) and the U.S. Public Interest Research Group (US PIRG), filed Wednesday, asks the FTC to investigate Microsoft’s use of customer data collection in its Web advertising service, called adCenter. The adCenter service targets customers with contextual advertising based on their Web habits.”

For advertising networks and advertisers, behavioral targeting is the next big step. Why only target based on on-page content when you can target ads with that content and that user’s interests, based on a recorded history?

Privacy is a huge issue. However, I am not convinced its going to be a show stopper. The AOL data leak resulted in quite an uproar.. for about 5 days. Is anyone going to care if Microsoft shows them new cars ads because they looked up the new Corvette yesterday?
