There is a lot of evidence that advertising has a much greater effect on children than on adults, which is why companies like marketing to children. They tend to believe what they see more than adults do, and as they are not old enough to make an informed decision they believe that they 'must' have the things they see on TV, and make themselves and their parents miserable by nagging for these things. Also. A lot of the products aimed at children, such as fast food, are actually harmful.
