If TV does not affect behavior, then why all the millions spent on commercials?
To give us some time to go to sleep so we will stay awake when the program is airing.
My wife is a teacher and it is almost impossible today to teach without visual aids -- a DVD is the most effective method to get any idea into teenagers' heads. I don't think that kids are wired today to learn anything without seeing a video.
So yes TV does affect behavior otherwise we wouldn't be spending so much money producing learning videos.
People who claim that what they (or anyone else) watches, reads, listens to etc has no affect, your argument proves it to be a lie.
