Google Gadget Ads

Google AdSense Blog http://adsense.blogspot.com/2007/09/introducing-google-gadget-ads.html announced that Google launched Google Gadget Ads, customized "mini-sites" that run as ads on AdSense publisher websites. These ads are interactive, engaging, and will appeal to your users, simultaneously providing value to advertisers while getting visitors to stick around your site. Gadget ads enable advertisers and agencies to engage audiences on the Internet's largest ad network with a rich and interactive new ad format. Think of gadget ads as mini versions of your website in any AdSense ad size.
Google Gadget Ads are nearly identical to Google Gadgets, except that they run as rich media ads on the Google content network. By adding a small bit of code called a click URL to your Google Gadget, the gadget becomes a Google Gadget Ad, capable of running as an ad on thousands of content network sites. Otherwise, the two can be identical in their basic construction and content. See
