Gary Price, news editor of Search Engine Watch, informed me of a blog entry at Adrants about a new contextual ad program. This contextual ad program is unique, in that it displays relevant video ads based on the content of the page. VidSense.com is the name of the program. VidSense "categorized the video content into a multitude of channels" and displays the relevant ad based on your content.
I have posted a thread on this topic at Search Engine Watch Forums.
