Television (also, informally, "TV" and "telly") is the electronic transmission of moving pictures. The word "television" literally means "far sight"; it was formed by combining the Greek word τῆλε ("tele", or "far") with the Latin word visio-n ("sight", from video, vis- to see) — this coinage follows the pattern of telegraph ("far writer") and telephone ("far talker"). A parallel constuction may be found in German, where it is known as "fernsehen" or "far-seer." In general usage, the meaning of "television" has been expanded to also refer to receivers, and to video in conventional broadcast as well as cable and satellite signals.The word is also used to describe, in broad terms, the content of television programming generally.
