The problem, especially with young children, is that they don't have a good grasp on what is truth and what is exaggeration -- or just plain fiction. In other words, children don't have that crucial "grain of salt" we adults take our advertisement with, until they're about ten years old. Younger than that, and they're easy and susceptable targets for the advertisement's message. If they see a commercial that tells them that all the cool kids have a Voltfire Extra Super-duty Cargo Train Robot Commander, they want one too. Young children are so vulnerable that some countries outlaw television advertising to children altogether.
Yet the vast majority of families in the US take advantage of their children in exactly the same way. Religious Indoctrination starts long before children have any hope of weighing the truth of what they are being exposed to. It amazes me to think of all the wars, all the deaths, all the suffering, and all of the hate that has resulted from the corruption of vulnerable children.
CARU, the Children's Advertising Review Unit has posted guidelines for what is and isn't suitable in children's ads. It's too bad nobody uses these guidelines for religious indoctrination, as it clearly voilates them. Read these segments from section 2b Product Presentation and Claims in their guidelines, and imagine it's talking about religious indoctrination:
To avoid deceptive and/or inappropriate advertising to children involving product presentations and claims:
1. Copy, sound and visual presentations should not mislead children about product or performance characteristics.
2. The presentation should not mislead children about benefits from use of the product. Such benefits may include, but are not limited to, the acquisition of strength, status, popularity, growth, proficiency and intelligence.
3. Claims should not unduly exploit a child's imagination. ... it should not create unattainable performance expectations nor exploit the younger child's difficulty in distinguishing between the real and the fanciful.
4. Advertisements should demonstrate the performance and use of a product in a way that can be duplicated by a child for whom the product is intended.
5. The advertisement should not mislead children about what is included in the initial purchase.
