The DoubleClick Ad Exchange: growing the display advertising pie for everyone
AdWords advertisers will be able to run ads on sites in the Ad Exchange, using their existing AdWords interface. This means more high quality sites for AdWords advertisers to run display ads on. Similarly, our AdSense publishers will benefit from more high-quality display advertisers coming through the Ad Exchange. You can read more about these benefits on the AdWords Blog and the AdSense Blog.
Great some time ago DoubleClick/Google declined my application to become a publisher :D.
I hope this will help Adwords customers and Adsense publisher as well. Maybe some Adsense publisher will earn now some while showing new/nice banner ads?
