Not really. fewer ads in a Hulu broadcast might be worth more as far as the depth of impression made. If you watch "Accidentally on Purpose" on TV, you might watch it because you like Jenna Elfman and think the show is funny. Or, you might just happen to be killing time between "How I Met Your Mother" and "The Big Bang Theory". Neilsen can't tell.
If, however, you watch Accidentally on Purpose on Hulu, it's because you want to watch Accidentally on Purpose. The ads that are targeted to that crowd are more narrowly and more properly targeted to you the Hulu viewer and shoudl be be more valuable per impression.
