BBC One

BBC One is the first flagship television network of the British Broadcasting Corporation (BBC) in the United Kingdom, Isle of Man and Channel Islands. It was launched on 2 November 1936 as the BBC Television Service, and was the world's first regular television service with a high level of image resolution. It was renamed BBC TV in 1960, using this name until the launch of the second BBC channel BBC2 in 1964, whereupon the BBC TV channel became known as BBC1, with the current spelling adopted of BBC One in 1997.
