I wouldn't mind so much seeing commercials on TV if they weren't so damn LOUD. As it is, I am forced to mute each and every one of them. Some are actually watchable that way. And some are funny, like when they relied so much on the audio message that the video makes no sense without it.
I don't expect them to respect the customer and leave the volume button alone during commercials. This is probably one of those "industry-standard" things that laugh "choice" in the face.
It seems to me that video alone has much less impact than audio by itself. I wonder why, considering that images are a considerably larger portion of our memories than sounds.
