I rarely watch TV except for TCM (when they actually show good movies), Movieplex, and PBS. I don't put up with commercials unless there is a program I really really want to watch. I like to watch Frasier late at night but the commercials are even more frequent, and longer, than during the day or prime time.
Seems like 90% of the time, when I am channel surfing, every single channel i go to is running a commercial, and they go on and on for so long I finally give up and turn the TV off.
That is one thing I like about watching soccer -- you get 45+ minutes of uninterrupted action, then a commercial break, then 45+ minutes more of uninterrupted action. And it's live. I don't have the patience to watch American football anymore.
