WHAT IS THE TELEVISION?
WHO WAS IT INVENTED BY?
CHANGES AND EVOLUTION
Television is an electronic system of transmitting transient images of fixed or moving objects together with sound over a wire or through space by apparatus that cover light and sound into electrical waves and reconverts them into visible light rays and audible sound.
The first person to produce a working television system was John Logie Baird, a Scotish man who was living in England. His 'televisor' system was based on a rotating disc that Gottlieb Nipkow had produced some 30 years before in Germany. Nipkow saw the potential for the disc but he never developed it into a practical application.

The screen can be glass with phosphorescent material on the front. The inside is empty of things to produce the deviation of the 'jet' of electrons to each part of the screen. There are four coils of copper wire to form two magnets.
