The issue is that Google TV is layering their ads and content on top of the television that the networks pay lots of money to acquire. So the networks pay all the costs and Google piggy-backs on it for free.
If you go to a network's site on your computer and view their content, you also view their ads. If you go to a network's site using Google TV, you view their content and their ads. Where do Google ads come into this?
No, this is all about networks being obsessed with distribution control - you can watch a show on your computer, on your HTPC, but not on a user-friendly HTPC. You can watch hulu on your laptop on your lap, but not on your tablet on your lap, etc etc.
So the more popular a television show, the more ads Google gets to show around it, and the more money Google makes. How much of that money gets shared with the networks that actually paid for television show and the costs of distribution? None. And that's the problem. The networks are putting up all the money and Google collects when it pays off.
No you don't.
