George Gerbner was the founder of the Cultivation Theory which investigates the effects of long-term television viewing.

It was based on his research that mothers are wary of how much television their kids watch and to us a real pain in the neck. But there are some resounding truths in this study which I agree to. The fact that we wouldn't know what affects us until we've seen it and the fact that what we see is all stored in the subconscious part of our mind slowly forming out train of thoughts without us realizing it.
Not just television but I think media as a whole is part of the blame. Nowadays we see more depressed and troubled kids with issues of self-esteem, addiction, bad influence and the list goes on and on. The question is what happened to these kids? Forget peer pressure and all those teenage rebellious stage but focus on the sole source of the problem. The media.
Why I say the media?
Have you ever seen a plump model on a fashion magazine with wrinkles or maybe a bit of zits? Well, I can tell you that I have yet to see one. So far every model we can think or is portrayed to us as flawless beautiful women that all men want and "if every men wants those type of women who wants me?" is the question most teenage girls struggle with.
And sadly most of them arrive at the same conclusion. Plastic surgery, nose job, eyebrow picking, bust enhancement and all sorts of modifications. The result? the death of a normal teenage girl and the birth of a copycat with self-esteem issues.
There are so many more examples I could mention but in case of sensitivity I choose not to because the point I am trying to make here is "Is the future of our children not as important to us as how much we can sell"?
Some might argue with the "It makes them develop better thinking abilities". You know what I say? Cognitive Dissonance. How can they choose when the world has already chosen for them?
