So tired of marketing

Why is it I cannot buy a product for my child without a blasted commercial tie in? I don't want diapers or training pants with characters from TV on them. I want just plain old training pants.
Why can I not buy her plates and cups without the latest movie character tie ins?
Fast Food restaurants marketing the kids meals toys to movies that are made for adults. My 2 year old is not going to see "Indiana Jones" or "The Incredible Hulk", so why should she be subjected to toys from those films?
Why can't we have a choice between a non commercial item, and one that is?
