As Korean government is concerning about school violence and aggressive character of adolescents, they have established 'Shut down' policy and 'Cooling off' policy that limit teenagers' game playing for banning school violence. Even if I agree with some movies, games and TV shows affect them, the real cause of their behavior is the society which sets excessive value on the academic background than their real ability. Stressful teenagers who don't receive much recognition from teachers because of their school records or who concentrate too much on study without noticing virtue of being social and bright are easily influenced by the media. Therefore the media operates as a triggering device of them.
I Know my opinion is too neutral and I focused on teenagers since they become adults in the future usually persisting in their beliefs.
