Google Testing Animated Ads

After allowing image ads on their AdSense network, Google is now testing out animated images.

There are a couple interesting items to note:

• AdSense is a very automated ad serving system. Google relies heavily on users and publishers policing content and reporting it, with no editorial approvals before the image ads are launched.
  
  
• They're allowing a whopping 50kb file size limit. This is much more substantial than many sites allow.
