eBay Stumbleupon Novel Advertising Approach

From BeetTV
The company has recently introduced a novel advertising approach: Advertisers can sign up to have a particular Web page "served" into the process of "stumbling." Meaning, users who are looking for a topic and click a video to view will be shown a web page that matches the demographic and interests of the "stumbler."

Garrett explains that there are few of these pages served -- just about one in twenty "stumbles" find an inserted advertiser Web page. We assume that the page loads for a limited time and then leads to the requested video.
