Advertising is a pervasive influence on children and adolescents.
Young people view more than 40 000 ads per year on television alone, and increasingly are being exposed to advertising on the Internet, in magazines, and in schools.
This exposure may contribute significantly to childhood and adolescent obesity, poor nutrition, and cigarette and alcohol use.
Media education has been shown to be effective in mitigating some of the negative effects of advertising on children and adolescents.
