But it's on network TV!

Last week I was watching one of the seemingly unending stream of Law and Order spin-offs when the plot suddenly hit me. The main characters of Law and Order SVU were lamenting the violence in a video game that a bad guy was using as the basis for his crimes (the game was clearly intended to look like Grand Theft Auto). Now if the shock there did not hit you it may be because you are not a fan of the show, but the graphic violence portrayed on the TV show often is more, well, graphic then the game's violence (the one in the show) that they were speaking against. In that moment I saw myself, and probably millions of others, thinking that violent games are bad while receiving that message from a violent show. So all of this got me thinking. When I was a child the worst show on TV was The Dukes of Hazzard (they disobeyed the law and disrespected authority) and the worst game was Pac-Man (he ate PILLS, someone might try to copy that). The world has become less innocent today as network TV involves graphic violence and near nudity and video games offer the same thing. So all of this leads me to some questions.

Does the media (TV, Games, and such) affect us? Can we have those images poured into our heads without there being an effect? How much time do you spend in TV and games like this? What do you think the Bible says about this? How about your friends?
