I guess advertisers think we are all f***ing stupid

Another thing about advertising that's been the last handful of years that pisses me off (all advertising not just car commercials) is when I'm watching something and it goes to commercials I flip the channel. Guess what. No matter what other channel I choose THEY are also on a commercial. W T F? Talk about collusion, monopoly, etc
I thought these channels were competing for out attention..... Yet every one knows when every other one goes to a damn commercial.
