An increasing concern is the high rate of violence displayed by the youth of today's society. Indeed, we are living in an age where violence has become a way of life. We have, in fact, become a culture of violence. Within the past three decades, there have been countless examples of man's inhumanity to man. Humans have more than proven themselves to be an aggressive species. With the exception of rodents, no other vertebrates so consistently and meaninglessly kill members of their own kind. .
Aggression is defined as an intentional behavior aimed at causing physical or psychological harm or pain to others. Aggression may be an act stemming from feelings of anger aimed at inflicting pain or injury, or it may be an intention to hurt another person with the hurting taking place as a means to some goal other than causing pain.
For centuries there have been disagreements over whether this aggressiveness is an innate, instinctive phenomenon or whether such behaviors are learned. However, one of the world's leading experts on human aggression, Leonard Berkowitz, among many others, believe that learning plays a very important role in human aggression. In fact, many studies have been done to prove indeed the amount of violence viewed on television by children is significantly related to the seriousness of criminal acts later performed as well as the likelihood of aggressive episodes. While television is only one of the mass media that affect children's behavior, it is certainly the most influential.
There are few developments in society that have had a greater impact on children than television has. In fact, television has become perhaps our single most important source of information. At the most critical time of social development, the average child spends about 20,000 hours in front of a television by the time he/she graduates from high school which is greater than the number of hours spent with parents or even in a classroom.
