Violence on television

Does violence on television play a major role in the behaviour/development of a child? In my opinion, it does because children are like sponges.  They take in everything they see and later on they will eventually do it.  It's somewhat like a "Monkey see monkey do" type of thing.  If a child constantly watches violent movies, you will notice that the child will become more aggressive.  Anyway, enough of my blabbering, what is your opinion?
