Television, or TV for short, (from French télévision, meaning "television"; from Ancient Greek τῆλε (tèle), meaning "far", and Latin visio, meaning "sight") is a telecommunication medium for transmitting and receiving moving images that can be monochrome (black-and-white) or colored, with or without accompanying sound. "Television" may also refer specifically to a television set, television program, or television transmission.

History of TV

The first images transmitted electrically were sent by early mechanical fax machines, including the pantelegraph, developed in the late 19th century. The concept of electrically powered transmission of television images in motion was first sketched in 1878 as the telephonoscope, shortly after the invention of the telephone. At the time, it was imagined by early science fiction authors, that someday that light could be transmitted over copper wires, as sounds were.
The idea of using scanning to transmit images was put to actual practical use in 1881 in the pantelegraph, through the use of a pendulum-based scanning mechanism. From this period forward, scanning in one form or another has been used in nearly every image transmission technology to date, including television.
