Ads in the iTunes and Podcasts?

AdAge.com reports that Apple is planning on incorporating ads into iTunes -- at least in a limited way.

The information comes from content partners who have reportedly been briefed on the plan.

Apple's current 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.

The area is typically reserved for album covers, but for Podcasts could be a location to display sponsored ads. The commercial viability of Podcasting has been questioned a number of times as its popularity has grown.
