My son is a prime example of an advertising sponge. As we drive along, he can see signs for businesses, and recite their slogans and campaigns. I am a tv fan, but his recitations have hit the point that we were discussing having the tv disconnected.
When he was younger, channels like TreeHouse were ideal, since their ads are very minimal, and usually balanced out with little shows on eating healthy, staying active, etc. But, now that he's older, TreeHouse is a bit below him, and the older channels are swarming with ads for HotWheels, Transformers, and a million other products.
Even though he's a slim, active little kid and I don't worry about unhealthy food adverts impacting him, since I still do the shopping and refuse to buy junk, I like the idea that he might have some slogans and jingles running through that little head of his that are health based.
