The word 'tele' means 'distance' and vision means sight .so television is a thing that carries out photographic pictures along with our voice to the farthest corner of the world. it is the most up-to-date means of communication.
The idea of television came first in the mind of Paul nijskow,a German scientist. He explained that idea of scanning a picture by breaking it up into small elements of light and shade .a number of scientists worked hard for quite a long period .at last an English named Beyard was able to invent television in 1945.
