Apple Selling Ads on iTunes?

ValleyWag claims that Apple is recruiting for an ad sales director in an effort to bring advertising into the iTunes store.

In a deal that should bring in several hundred million dollars off the bat, the company will run ads, most notably on its iTunes store.

The article has few details but suggests that Google's ad system would be used.

This is not the first time that there have been rumors of Apple incorporating ads into iTunes. An AdAge article from April 2006 indicated that Apple was looking into publishing ads while users listen to podcasts:

Apple's [April 2006] plans call for the ads to appear only in the lower-left corner of the iTunes library while users listen to podcasts from their computers rather than from portable devices.
