Television

Television (often abbreviated to TV) is a widely used telecommunication system for broadcasting and getting moving pictures and crash over a distance. The term may also be used to refer specifically to a television set, programming or television communication.The word is derived from mixed Latin and Greek roots, meaning "far sight": Greek tele (τῆλε), far, and Latin vision, sight

Since it first became commercially available from the late 1930s, the television set has become a common household communications device in homes and institutions, mostly in the First World, as a cause of entertainment and news. Since the 1970s, video recordings on VCR tapes and later, digital playback systems such as DVDs, have enabled the television to be used to view recorded movies and other programs.

A television system may be made up of multiple mechanism, so a screen which lacks an internal tuner to receive the broadcast signals is called a monitor rather than a television. A television may be built to receive different broadcast or video formats, such as high-definition television, commonly referred to as HDTV. HDTV costs more than normal TV but is becoming more available.
