BBC One is the flagship television channel 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 sister channel BBC2 in 1964, whereupon the BBC TV channel became known as BBC1, with the current spelling adopted in 1997.
The channel's annual budget for 2012–13 is £1.14 billion. The channel is funded by the television licence fee together with the BBC's other domestic television stations, and therefore shows uninterrupted programming without commercial advertising. It is currently the most watched television channel in the United Kingdom, ahead of its traditional rival for ratings leadership, ITV.
As of June 2013 the channel controller for BBC One is Charlotte Moore, who succeeded Danny Cohen initially as Acting Controller from May 2013.
In 2012, the BBC out-bid ITV for the rights to The Voice UK, which had already proved to be popular in other countries. The BBC paid £22 million for the rights to broadcast the show in the UK for two years. The Voice UK achieved good ratings for the BBC but ratings dropped towards the end of the first series and the second series. In 2013, The Voice was rescheduled to avoid a clash and as a result ratings have improved.
