I could just be overreacting, or just being somewhat onerous (lord knows I never do that), but it seems to me that there is a fair amount of misinformation used in rather a lot of public health campaigns.
Take this new "Syke" campaign against teen smoking. On their front page, as an example of the ways that the vile, odious cigarette companies attempt to manipulate pure, innocent children, there is an old ad spot from the Flintstones in the sixties for Winston brand cigarettes. I'm going to go out on a limb here and reckon that the people running this campaign weren't actually alive when the Flintstones originally aired, else they'd have known that the cartoon was played during "prime time" and intended for an older audience. They appear to be working off of the long-standing but fallacious assumption that cartoons and comics are, were, and always will be for children and no others.
This societal specification of cartoons as a source of entertainment limited to children has helped mark what is socially assumed to be the maturation of children into adults for decades. When children stopped watching cartoons and started watching whatever insipid teen oriented programs that existed, they were thought to be "growing up." Among other things it created a boundary for the play and entertainment of children and adults, further enforcing a social divide between the age groups necessary in order to maintain the "inherent" dominance of adults and inferiority of children. When children were willing to forgo their "traditional" forms of entertainment, then they were allowed the privileges (and responsibilities, in most cases) of adults.
Anyway, it does destroy a tiny bit of credibility for the campaign to make such an erroneous assumption, regardless of its ubiquity.
(If this post were pretentious, I would have said "irregardless" instead)
