BBC One (or BBC1 and BBC 1) is the first and flagship television channel of the 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 in 1997.
BBC One is currently broadcasting the Scottish television crime drama Shetland that is produced by ITV Studios for the BBC.
