TV is one of the most popular way to spend our time. Nowadays more and more teenagers spend twice as mush time in front of the TV than reading books or playing games outside. As far as I know there is a great variety of opinions about television: some say that it's very useful, and the others that it's harmful.
I would like to mention some possitive aspect. In the first place, it keeps people informed. There is news, which inform us about the things, which are happening all around the world. Besides advertisements on TV give us information about different products and it makes easier to choose things to buy. Moreover, it is one of relxing forms. TV shows entertain people when they are tired or lazy to go out. Most of the youth like TV channels like MTV or VIVA because of great variety of music clips and others entertaining shows. And finally, it is a kind of learning. There are a lot of documentary films, which show us the life of wild animals, old civilizations and art creation. .
But TV has a lot of disadvantages too. The first one is that there are a lot of violence and debauchery in TV films, even in cartoons. And violence has a bad effect on children and teenagers. They can't understand what is right or what is wrong and sometimes try to copy that they have seen. Furthermore, there are too much advertisements on TV. It is really irritating agent, which get people danger up. Sometimes it can encourage us to buy things we don't need at all. Last but not least, watching TV takes a lot of time and it makes us lazy. Some people believe, that it is a waste of time, a time which better would be spent on doing more useful things like reading, working an so on.
In conclusion, people need TV, but it can't be the main thing in their life. In my opinion we need TV despite of it's disadvantages. People need something like an information center. For example, I watch TV about two hours a day.
