George Gerbner, who came up with the Cultivation Theory, claimed that because television contains so much violence, people who spend the most time in front of the television set develop an exaggerated belief in a mean and scary world. Gerbner defined dramatic violence as “the overt expression of physical force as part of the plot.” This “dramatic violence” rules out verbal abuse and idle threats but includes the physical abuse present in cartoons. The exposure of these heavy amounts of violence on the television can cause people to create an abstract world where the victim of similar violence in real life would be fine. I have seen numerous videos on YouTube of teenagers and young adults doing numerous wrestling moves in an unsafe environment, clearly not concerned with the danger of the various maneuvers they were performing.
