A television (also TV, telly or tube) is a machine with a screen. Televisions receive broadcast 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 TV 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.
A television can show pictures from many television networks. Computers and mobile devices also can be used for watching television programs. At first, all televisions used an antenna (or aerial). This would pick up television programmes from broadcasting stations. A TV station could be many miles or kilometers away, and still be received. TVs can also show movies from VCD and DVD players or VCRs. Cable TV and Satellite television can provide more programs at once than broadcast can. Video game consoles connect to most modern TVs. Some computers can also use a TV as a computer monitor.
