The thing I found really interesting was the $20-$40 CPM. That's WAY bigger than everything else on that list. But that comes at the cost of the podcast creator's word that the product that's being advertised is worth it. The thing that worries me is where is this leading?
Are other entertainment mediums going to have to do the same thing to be profitable? What about when advertisers want to sponsor podcasts about their product (like a video game podcast being sponsored by Call of Duty)?
