Chicago's Video Game Advertisement Conundrum

I was born and raised in Huntington, but I currently live in Chicago. Here's what's going on on this side.

This is a Chicago Transit Authority bus in Chicago, Ill. It's how I get to school every day. When I look at an advertisement on the bus, I tend to think that I'm not too easily sold on the sandwich they're waving in my face while I try not to fall onto the little old lady standing next to me. However, some Chicago officials believe that these ads are WAY more persuasive than you'd think.

According to Chicago's local Fox News affiliate, the CTA is going to take down all of their Grand Theft Auto IV ads - an ad campaign that can't be cheap. Why? Because the governor and the president of the CTA believe that it's a negative influence on children.

I see these ads every day. I see stickers on newspaper boxes down the street that say GTA IV. I have never been compelled to run out and buy it immediately. Yes, kids may be more influenced by an advertisement than I am, but is this really necessary? Isn't it up to the parents as to what the kid is playing? Are these advertisements worse than subjecting kids to the violent nature of being on the train during rush hour?

It's noble, but is it really necessary?
