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.
