It’s finally here. YouTube has started video advertising, allowing ads on the site that include video. It’s only natural, no big surprise here. They have, however, created something kind of cool in Brand Channels, wherein advertisers can have their own channel to push all their stuff down. The first such channel is…….The Paris Hilton Channel. Of course. Paris, remember, was also one of the first commercial podcasters when she was promoting her House of Wax movie. Let’s hope marketers don’t just shove the same old crap they serve us on tv and radio down this hot new medium.
