The Competition Bureau is beginning a preliminary examination of behavioural targeting and of the marketing model that drives a lot of this kind of advertising. They've been looking at children's privacy and the impact on children. As an unfair trade practice, there is space there to examine it.
In addition, I think it might be worthwhile to think about some kind of regulatory framework or legislation that might set some standards for body images in advertising. I think that would be amazing, because you're right; when we look at the Dove ads and we see regular girls or regular women up there, it's like “Whoa!”
If we could change the visual environment that children live in, it might actually have an impact. I would suggest you consider that as a possibility as well.
