WhatBusinessModel? writes "In another blow to online banner advertising, Ask Jeeves is announcing that it will stop running banner ads on its website in favor of more paid listings. Says Steve Berkowitz, president of Ask Jeeves Web Properties, 'I think banners have seen their day. They're not as compelling as they once were.' In contrast, he describes paid listings as 'kind of a next evolution of the yellow pages.'"
Probably a change that will become more and more prominent in the search engine world.
