Kids also tend to disobey, and whine about it. Sure you can say parents should be strict and thorough, but you can’t expect 100% of parents (who are often tired from a hard day at work) to be 100% diligent 100% of the time.

And the reason we have these ads is that corporations are hoping that the kids will indeed disobey, and whine constantly at their parents, until they have their way (as directed to by the targeted ad). There was a good reason why targeting kids in ads used to be illegal in Europe.
