I think sometimes parents just aren't aware of the effects of particular program elements on their kids. Parents today are very busy. The circumstance in most households is that both parents are working. They're harried, trying to keep up to speed with everything from homework to hockey practice to ballet class. Trying to dump something else on them is a challenge. I know I've been there.
It would be up to the folks at the Media Awareness Network, who are the experts at this. There are all kinds of initiatives I think they would like to pursue that would be beneficial to parents, like maybe a little pamphlet on a milk carton or something like that. All of that takes money, time, and organizational ability. They just don't have the resources to do that.
