单选题 Television, or TV, the modern wonder of electronics (电子学), brings the world into your own home in sight and sound. The name TELEVISION comes from the Greek work TELL, meaning "far", and the Latin word VIDERE, meaning "to see". Thus, television means "seeing far". Sometimes television is referred to as VIDEO, from a Latin word meaning "I see". In Great Britain, the popular word for television is "telly".
Television works in much the same way as radio. In radio sound is changed into ELECTROMAG NETIC(电磁波)waves which are sent through the air. In TV, both sound and light are changed into electromagnetic waves. Experiments leading to modern television took place more than a hundred years ago. By the year 1920s, inventors and researchers had turned the early theories into working models. Yet it took another thirty years for TV to become an industry.
As an industry ,TV provides jobs for hundreds of thousands who make TV sets and broadcasting equipment. It also provides work for actors, technicians, and others who put on programs. As an art, television brings the theater and other cultural(文化的)events into the home.
