In addition to Google’s AdSense network there are a number of other competing networks, including Yahoo Publisher Network, Kanoodle BrightAds, etc. It would be great to see a competitor to AdSense where all of the proceeds went to charity. I’m imagining a network called AdsForGood or something like that. The company that operated the network could just take enough of the ad revenue to cover their operating costs and all of the rest would go to charity (including the site publisher’s portion).
