Television

Television is an important means of entertainment. It has great educative value. We can see pictures and listen to the conversations among the world famous personalities. Television was first invented by John Baird, a famous scientist of Scotland. Mr. Baird demonstrated his invention at the Royal Institute of Great Britain in 1926. The mechanism of television  is very complex. A television camera has photo electric cells which receive pictures and transform them into electric dots and lines. Those dots and lines are then transmitted to the receiver set. The receiver set again transforms those dots, and lines into pictures. A general people can not even think how it works. Through television we can see drama, musical functions, and speeches which are held in distant places. At the same time we can hear the music and the talk of those speakers, musicians or of the actors in the drama. Television has great educative value. Thousands of students are being benefited through many programmes. Very often television exercises bad influence upon the youngsters. Rape, murder and violence are adopted by those young people who usually see these things in television. Young children may be affected by the abuse of it. TV programme should be made carefully.
