Television has a big impact on the way we spend our free time. It probably affects younger people more than adults, as they watch more TV.  Critics of television claim that TV takes away too much of our free time so that we lack time for otheractivities like family conversations, reading, getting excersise etc..
It also shows us a world that is not real.  Television often encourages us to think that the world is more violent than it really is. Through TV we perceive the glamorous life of people and believe that they are better off than we are.
Television contributes to our education and knowledge. Documentaries and information programs give us insight on nature, our environment and political events.
Television has a huge impact on politics. In election years, discussions, speeches and campaign news of candidates are broadcastalmost every day. Political parties buy TV time to present their views and bring ideas to the audience.
Sports attract the biggest audiences on television.  TV stations pay enormous amounts of money to broadcast big sport events, like the Olympic games, or professional basket, football and baseball. Because of television some sports have gained popularity and more and more people engage in them.
