It looks like the integration of AdSense ads into Feeburner feeds is a step closer with reports surfacing that AdSense ads have been seen on RSS feeds that look like this.
This ad was seen on the feed of Inhabitat (found via Digital Inspiration). The images are served as image maps not JavaScript.
Here’s hoping that this will perform better than the previous AdSense for RSS program that has been in beta for a couple of years now!
