Television

Television (also informally "TV" and "telly") is the electronic transmission of moving pictures over a distance. In practice, most television transmissions also include synchronized sound, a common exception being surveillance cameras. In general use, the word has been expanded to refer to the receiver, and to both the video broadcasting industry and its programming.

"Television" literally means "far sight"—its coinage was based on the earlier "telephone", or "far talker". The two parts that form the word are a combination of the Greek word τῆλε ("tele", or "far"), and the Latin word visio-n ("sight", from video, vis- to see)).

Broadcasting development

After many years of research, the first regular television service in England began operation in 1936. Initially, the British Broadcasting Company alternated between John Logie Baird's 240-line mechanical system, which employed scanned film as an intermediary, and EMI-Marconi's 405-line "System A", which used Vladimir Zworykin's all-electronic setup. Tests of the Baird's system were ended after four months. And the outbreak of the Second World War caused the BBC service to be suspended on September 1, 1939, not to be resumed until June 7, 1946.
