Television (TV)

Television (TV) is a widely used telecommunication medium for sending (broadcasting) and receiving moving images, either monochromatic ("black and white") or color, usually accompanied by sound. "Television" may also refer specifically to a television set, television programming or television transmission. The word is derived from mixed Latin and Greek roots, meaning "far sight": Greek tele (τῆλε), far, and Latin visio, sight (from video, vis- to see, or to view in the first person).

Commercially available since the late 1930s, the television set has become a common communications receiver in homes, businesses and institutions, particularly as a source of entertainment and news. Since the 1970s, recordings on video cassettes, and later, other media such as laserdiscs, DVDs, and Blu-ray discs have resulted in the television frequently being used for viewing recorded as well as broadcast material.

A standard television set comprises multiple internal electronic circuits, including those for tuning and decoding broadcast signals. A display device which lacks these internal circuits is therefore properly called a monitor, rather than a television. A television set may be designed to handle other than traditional broadcast or recorded signals and formats, such as closed-circuit television (CCTV), digital television (DTV) and high-definition television (HDTV).
