Answer:
A television (also known as a TV) is a machine with a screen. Televisions receive broadcasting signals and turn them into pictures and sound. The word "television" comes from the words tele (Greek for far away) and vision (sight).
Sometimes a television can look like a box. Older TVs had a large cathode ray tube in a large wooden frame and sat on the floor like furniture. Newer TVs are much lighter and flatter.
