Mass Media

Nowadays information communication is an important part of our life. It goes without saying that mass media has become an integral part of modern people's life.We live to learn news; we breathe and live with this.

Let's concentrate on one of mass media branches — television. As we know, it appeared much later than such kinds of mass media as radio, newspapers and magazines. Television now plays an important role in our life. It takes a steady place in our daily timetable. However, watching television has two sides: not only advantages but also disadvantages.

On the one hand, TV keeps people informed of current events; TV gives us wonderful possibilities for education. We can choose any programme according to our interests, mood and needs. It can be the sphere of politics, news, sports, animals, feature films, soap operas, art, talk-shows, cartoons, educational programmes, music, fashion and many others.

The second advantage of watching television is that it gives families an opportunity to spend some time together. Nowadays adults are often too busy to give enough attention to their children. When they come home from work in the evening, so tired and exhausted, — the only possible way to relax for many is just lay on the sofa in front of TV In such situations it's high time to choose a family comedy and see it together with your spouse and children.

Nowadays you are not limited in your choice, for even if there is no film you'd like to see in a TV-programme, you can always see it on DVD or download it in the Internet.

However, watching television has its negative side. It is well-known that television may turn to be harmful for our health. Spending too much time in front of a TV screen may affect our eyesight badly. Their progress in studies suffers due to the fact that children try to do their homework as fast as they can in order to have more time for watching TV.

Moreover, nowadays some TV programmes and films include a lot of violent scenes that can have a negative influence on a child's psychic development.

Another disadvantage of television is an enormous amount of advertising. Firstly, it makes people buy some useless or unnecessary things.. The result of it may be the fact that children become too much concentrated on their appearance, which may lead to depression or to the feeling of inferiority.

Finally, many children nowadays would rather spend a day glued to a TV-set than go outdoors to play with their peers.

Undoubtedly, we need TV, for it is one of the main and most convenient means of mass media. However, taking into account all its merits and drawbacks, we must try to organize our time in the right way so as not to become a TV slave
