The major concern is the effect of violence, due once again, to studies that show a connection between watching violence and participating in it. For example, Bushman and Anderson (2002) conducted as study in which they determined that playing violent video games can "engender hostile expectations, leading one to expect that others will respond aggressively" (p. 1679). The Grand Theft Auto series of video games has undoubtedly been a major instigator in the backlash against the gaming industry. Not surprisingly, most parents are not too thrilled about the idea of their children taking on the persona of a character who commits crimes to earn rewards, and runs over prostitutes so he doesn't have to pay them. There was also a major parental backlash against the PS2 game Bully before it was released, because parents assumed that it would glorify bullying. The frenzy turned out to be unfounded as the game was actually very tame and did not advocate bullying at all. However, anyone watching the news lately can see that...

It is a two way street between the manner in which these two elements of society affect one another, and it probably always will be. Television, movies and video games have become such an integral part of our modern culture they are blamed for everything from racism to violence to materialism to anorexia to obesity. Good or bad, this is a connection that is much too strong to be broken any time soon.
