Given that on of the most popular ebook formats are based on HTML it requires only fairly obvious adaptation of exsting technologies to provide ebook ads.

Yahoo's patent seems to be for contextual and links ads in ebooks instead of web pages.

I refuse to buy DRMes ebooks so I have bought very few, although I read lots of free ones.
