Anti-drug commercials, public service messages that talk about the dangers and damage of illegal drugs, are common on television in the US, at least when I'm watching they are, and the movies I get, on basic cable, have profanity - like the words "shit" and "fuck" - bleeped out or, in a more modern and less noticeable solution, overdubbed in matching tones that blend relatively seamlessly with the dialog.
It's clear that the moral forces behind these adjustments believe that televison has coercive power, and that seeing and hearing things on television has a direct effect on people, especially children.
So what do you think the effect on children of a constant barrage of commercials for cars and trucks is? What's that doing to kids? What does it teach them about what's good, what's approved, how things are, and how they should be?
