According to Wikipedia in their article for McDonald Land...
As obesity has become a growing problem in recent years, McDonald's and other fast food chains have been under increasing pressure to revamp their products and advertising with healthier alternatives. As part of this campaign, McDonald's has agreed to discontinue marketing to children under the age of twelve.
This to me is complete horseshit. Yes obesity is a growing problem but no McDonalds and fast food are not solely to blame. In fact they are a small small part of the blame. Kids have been eating McDonalds and drinking pop for ages and why is it that obesity is started to become a problem now? Because instead of eating the fast food and drinking the pop and then going out and running off the pounds in play Kids today come home and park their ass on the TV to play PS 3 and XBOX 360 or they are on the computer.
Kids eating habits haven't changed their physical activities have.
