The next logical step: offer feeds for commercials as a podcast of vidcast.
True, most people don’t like to watch commercials. But if someone is a fan or even an advocat of a brand, he/she will most likely want to watch every spot that is newly released.
And then there are those people generally interested in good TV commercials (just think about the fact that lots of people like to watch the Super Bowl commercials or the Cannes Roll.
So why not offer these people a feed, where they are notified whenever a new spot is available? That way, they can TiVo all the other ads on TV and still see the spots they like.
Does this work for every Brand, low as well as high involvement brands? Probably, if their TV spots are entertaining enough.
