The GooTube team is not inserting advertising into YouTube clips as post or pre-rolls. That might happen, but not quite yet. Chad Hurley has said that in-clip ads would not be appreciated by the YouTube user base. He may be right.
So, to the monetize the extraordinary traffic on YouTube, the Google folks are doing it the traditional way — by placing banner and contextual ads around clips and channels and other indexed pages.
We discovered that those clever folks at Google are expanding their advertising offerings by selling "pop-up" ads. While searching for clips by presidential hopeful Dennis Kucinich, we came across this pop-up ad for Best Western Hotels. When the page loaded a large banner opened and Flash video player that launched a 20 second video ad that was on a continuous loop. The page with ad is above.
