Google Changes Again
It's safe to assume that this new change will result in the kind of graphical ads that have been delivered by other networks showing up on this network as well. Many if not most website owners are unhappy with such ads from rival advertising companies because they are 'too obvius' and visitors generally tend to ignore them. Publishers can choose not to display image ads. One such publisher is google.com! . They have stated that image ads will not be displayed on the google search results pages.
Let's hope that the same fate does not await the adsense graphical.
