There are so many incidents caused by violence in mass media. For example, the Columbine High School incident, in which two young boys who acted violently allegedly played many hours of violent games, allegedly acted accordingly. They killed 12 students and a teacher. He also injured 21 other students and then committed suicide. People are not interested in the bigger problem of fighting these mass media production companies. Instead, many people ignore the problem. Most children watch and play them without knowing what is reality and what is not. And what's right and what's wrong. This media also promotes inappropriate scenes that children should not participate in.
