Ok, i am not in the US, so i can only comment on what i can see "from here" ;)
But to me it looks like hulu.com is a webservice average joe user doesn't use anyway.
What counts is tv ads, posters, magazine ads and the likes.
What i have seen is, that Verizon/Motorola did a lot of advertising (super bowl ad, etc.). Now, google does hulu ads. thats a whole different level.
