Cultivation Theory, developed by George Gerbner, says that television shapes our perception of reality. An example of this theory is if viewers watch a large amount of violence on television, they perceive our world as more dangerous than it really is. This is called the "mean world syndrome". Cultivation Theory tells us that some people watch outrageous shows on television and see them as reality when in fact they aren't even close to our reality. The video below displays how cultivation theory can occur in real life.
