The claim is that Hulu Plus subscribers watch less commercials, but it that really true. And if there are less commercials, how much less? I'm a bit skeptical when Hulu marketing info states that paying subscribers help keep costs down. The reality for all advertising business models is to maximize profits through advertising. If Hulu has companies buying ad time for for TV series XXX, I can't see them turning down money because they have a policy of only couple minutes (or whatever) of ads for paying subscribers. I would suspect that if they could match the networks with 18-19 minutes of of ads per hour, Hulu would do it.
