Television

Today a television is found in almost every house across the world. The rich, the poor all have it and it is one of their most entertaining possessions. However, the television that we see today is completely different from its predecessor in a number of ways.

The first televisions were very basic and started appearing in the early 1800s. Though, they were rudimentary and worked purely on mechanical principles. The concept involved scanning an image and then transmitting it onto a screen.

A major breakthrough came when the mechanical scanning system was combined with a cathode ray tube in 1907 by a Russian Boris Rosing and English A.A. Campbell Swinton.
