Television - blessing or a curse?

In 1928 John Logie Baird discovered television. TV-set was great and very powerful invention. But it generally believed that television has many good and bad points.
I will try to point them.
First of all - watching TV is cheap and comfortable. There are a lot of channels. It is wonderful to have such a variety however there are programs which some might argue, have a very negative influence, especially on the young and children. In particular violence on TV.
As far as children are concerned they are easily influenced by trashly commercials and temped by junk food or expensive toys. If children watch brutal cartoons in future they may steal and kill other people. Theirs brains are young, they do not learn and do not read books, they prefer watching cartoons. Reading books can increase our inteligence and polish. Children science imagination is very poor.
There are full of very interesting channels as Discovery, National Geographic. They gives a lot of possibilities to take some knowledge about exotic and hard to visit places such as Africa, Asia and Australia. Also TV broadens our knowledge and gives many possibilities for example: domcumentary and nature films.
What is more, we can listen to music from whole the world on music channels, like MTV or VIVA. And during watching foreign channels may be improve languages.
Telly is the most important source of information about what is happens in every corner of the world. There are many discussions about political and economical situation in country and aboutsome others things. TV is necessary for people who like to know what is going on in politics. But sometimes television do irreparable harm. It has become one of the major sources of political propaganda.
What is more - unfortunately, information may be subjective. Television may lie and finally we do not know the truth. We may argue with somebody and if we do not know the truth we may quarrel with somebody groundlessly.
The next good point is the materials which presents on TV are usually easy to assimilate and often are used by students at school and by teachers during the lessons.
On TV everyone can find something for oneself, but often TV may be dangerous. A lot of people who watch TV are telly addicts, because te television is a thief of our time. When we watch, the time goes faster, and we have not got it for things that are more important for us. It draws us away from active spending of our time like going to the cinema, the theathre or reading good books.
For examle, young people can not live without TV. However is it really so convenience for us? It occupies our time so that we can easily addicted to it. Furthermore, television promotes violence and fast-fleeting trends, so that a lot of people can fall in to complexes.
But fat people usually watch television more than slim persons. Plump persons are passive and do not train because they watch many soap-operas.
Moreover, TV stops peoples from talking. Families do not communicate their feelings and do not exchange impressions. Children do what they want because parents do not talk with them. Parents are often too busy working or taking care of the home, to monitor exactly what their children are watching at all time. Many times TV set becomes a substitute parents even a friend.
To sum up, television, since its creation was very popular and continues to be. Whether we like it or not, it influence, our thoughts, beliefs and behaviour. Whether the influence is positive or negative in the end it all depends on us.
