Google's Ad Manager

Google's Ad Serving Solution I love all things Google and actually think they should run for President. Something new from Google and straight from the horse's mouth "If you operate a site with remnant ad inventory as well as reserved ad inventory that you sell directly to advertisers, then Ad Manager is for you. It can help you sell, schedule, deliver, and measure directly-sold and network-based inventory."

Right now it's by invitation only and there's no charge to use it. If you go to the page above you can click on a link and request to be invited.
