You just don't realize it. You're not anywhere near as in control as you think you are. Like it or not advertising works. Not always, but lot and lots of times. It's especially effective on kids. Out of spite you might personally block your kids from consoles if you become aware that it's the advertising that makes them interested, but if so you're very much in the minority. Your opinions, beliefs and desires were heavily shaped while you were young and vulnerable, and so are your kids. The advertisers are more interested in iPad games because they're cheaper to make and just as profitable as an aggregate whole. We'll all do as we say because as kids we literally can't think for ourselves. That's why in the 60s and 70s Mr Rogers and others fought against advertising directed at children, and it's also why they lost.
