ITV, legally known as
Channel 3, is a British free-to-air public broadcast television network. It is branded as ITV1 in most of the UK except for central and northern Scotland, where it is branded as STV. It was launched in 1955 as
Independent Television to provide competition and reduce the current monopoly to the then BBC Television. ITV is the oldest commercial network in the UK. Since the passing of the Broadcasting Act 1990, it has been legally known as Channel 3 to distinguish it from the other analogue channels at the time: BBC1, BBC2 and Channel 4.
