Television

Television is a widely used telecommunication system for broadcasting and getting moving pictures and sound over a distance. The term may also be used to refer unambiguously to a television set, programming or television communication. The word is derived from mixed Latin and Greek roots, meaning "far sight”.

Commercially available since the late 1930s, the television set has become a common household connections device in homes and institutions, particularly in the First World, as a source of leisure 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 various components, so a screen which lacks an internal tuner to receive the televise 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 common TV but is becoming more available.
