Even such seemingly innocuous products as milk are being advertised to teens with sex. But I know a lot about girls. Gellar plays a scantily clad, super strong, teenage vampire slayer. They are very cleaver and some of consumers favorite ads. It's just a picture.
Advertising agents beware.
Word of mouth is the most efficient form of advertising. The problem is that the gatekeeper of teen culture is the teen's peer group. Teens move as a mass of mass consumers. No one seems to know who decides what's cool. That's where the difficulty in advertising to teens lies.
