Big ad news today from Google, they have officially made a big push into display ads through DoubleClick ad network they acquired a two years or so. The DoubleClick ad network will be directly integrated into AdWords. This expands the content network, which means AdSense publishers should see more ads, hopefully higher paying ads.
I am about to get on a plane, so let me give you all the relevant links that I can find. We have the main Google Blog discussing the integration and the AdWords blog talking about how this impacts search advertisers and finally the AdSense blog discussing how to get these ads in your mix. Greg Sterling covers more of the business angle at Search Engine Land and plus we have tons more commentary at Techmeme.
