WIRE BROADCASTING
Category: Cinema + TV/RadioWire broadcasting — a system whereby radio programmes are received at a central point, whence they are distributed by wire to listeners and viewers — began in the United Kingdom in 1925 as a private venture and remains in the hands of private enterprise. Wire broadcasting companies operate under licence from the Postmaster General. They are not allowed to originate programmes of their own, and their Junction is to distribute programmes from general broadcasting stations. A specified minimum of their programme material must be taken from BBC sources. Subscribers to wire broadcasting services must have ordinary broadcast receiving licences. At the beginning of 1958, there were 411 wrire broadcasting services, of which 105 gave television service and the remainder sound-only service. The number of subscribers at that date was just over one million, including 108,019 who were receiving television services.
