What is the most significant effect that watching television has on people?

Over the next few weeks, we are going to look at lot of different materials
about the role of television programs and television watching in people's lives. But first, I want to know what you think about this topic. So here is a question for the class discussion board: What do you think is the most significant effect that watching television has on people? Why do you think television has this effect?

I know that one way that television influences people's behavior is that when you are watching television, you are not moving around or exercising. This is especially true for children. The American Academy of Pediatrics says that when children spend a lot of time watching television they have a greater tendency to be overweight.

I think the main effect that television has on people is to broaden their experience. There are so many programs devoted to nature and travel. Think of all the different places in the world you can experience through television! Last night I watched a program about life in Antarctica and it was fascinating!
