I want my MTV

I like my MTV on a stick. I know I could become addicted to watching old sitcoms and cartoons on the computer. I prefer HULU to Joost. I've used HULU before so I am more familiar with it. I wonder if free TV is too good to be true. How long before I have to pay or get stuck watching ads before I view the show. I'm sure this is affecting TV stations. Just like email has affected the postal system. The main difference will be that TV stations will adapt and change inorder to remain competitive.
