Reports from DigitalPoint Forums and WebmasterWorld show proof that Google is testing out a scrolling ad feature with AdSense. Here are select images taken from forum uploads of how Google has implemented the feature, take notice of the small arrows on the corners of the ad.
As you can see in these four sample images, Google has added arrows up and down (or left and right). When you click those arrows, the ads scroll to different ads.
Google is constantly experimenting with different methods of enabling users to interact with the ads.
The overall reaction to this new ad format is positive, so far.

My research shows that the profit of some people (12 site owners who display AdSense ads) has decreased since Google added scrolling ads to service. Most of htem say that users scrool ads and when they don;t find something catchy, the just don't click on ads. At the same time Google charges advertisers for exposure.
