OpenX allows you to serve ads from different ad networks and rotate ads from different networks to find which one pays the best. With OpenX you can sell advertising directly to the advertisers and have their ads replace network ads. You can download OpenX and host the ads yourself for free or use their hosted solution which is free for up to 100 million impressions. The CEO of OpenX is Tim Cadogan, a senior VP at Yahoo. Google's AdManager product has similar features.
