Television, or TV, the modern wonder of electronics, brings the world into your own home in sight and sound. The name television comes from the Greek word tele, 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 electromagnetic 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 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.
Many large schools and universities have "closed-circuit" television equipment that will telecast lectures and demonstrations to hundreds of students in different classrooms; and the lecture can be video taped to be kept for later use. Some hospitals use TV to allow medical students to get close up view of operations.
In 1946, after the World War II, TV began to burst upon the American scene with a speed unforeseen even by the most optimistic leaders of the industry. The novelty of seeing TV pictures in the home caught the public’s fancy and began a revolution in the world of entertainment. By 1950, television had grown into a major part of show business. Many film and stage stars began to perform on TV as television audiences increased. Stations that once telecast for only a few hours a day sometimes telecast around the clock in the 1960s.
"... sometimes telecast around the clock in the 1960s. " means
