The word Television comes from the latin word 'tele' and 'vision'. The rerm 'tele' means distance and vision means sight.  In a word , Television means a sight from  distance. It is somewhat different fron a radio. From a radio we only get the vouce of the speaker. On the other hand, we get both the voice and the picture of the speaker from a television. Thus it has been proved as the best medium of all.       
Invention:
At first the thought of sending a picture to a distant place comes in Paul Nipkow, German scientist. But john Bayard, an English scientist was able to give this thought a real shape . As a result, we get Television.
How it works:
The function of a television is mainly complete through two parts. One is transmitter that changes the picture into eletro-magnetie wave. Another is the antenna that catches this wave from air. Then we get the picture.

It also plays an important role in education. It is being used to teach the students and illiterate people. It also arranged special  programmes for children, woman worders and soldiers. It is the best medium of being famillar with customs and traditions the world. So ti has a great appeal to the people of all classes.
Abuses of  Television:
Television in not only useful to us. It has some abuses too. Sometimes young boys and girls concentrate their attention so much on it that they froget everything. They forget about their suddies which is the main duty of the sudents.
Really, the Television is the charm of the age. It has brought a remarkable change in human life. It has become companion to the lonely people and friend to the friendless. It is now a part and parcel of everyday life. In a developing country like ours, importance of television cannot be ignored .
