Overture and Adsense are the most common ones that I know of, there is another one but it isn't as widespread as the others known as Espotting.
Are there any other ones on the market except for Overture who offers the same type of service to webmasters. With so much problems that I read on the internet about adsense, maybe it is better to have more than one advertising partner in your pocket. Anyone?
