Context: BBC TV was renamed BBC1 in 1964, after the launch of BBC2 (now BBC Two), the third television station (ITV was the second) for the UK; its remit, to provide more niche programming. The channel was due to launch on 20 April 1964, but was put off the air by a massive power failure that affected much of London, caused by a fire at Battersea Power Station. A videotape made on the opening night was rediscovered in 2003 by a BBC technician. In the end the launch went ahead the following night, hosted by Denis Tuohy holding a candle. BBC2 was the first British channel to use UHF and 625-line pictures, giving higher definition than the existing VHF 405-line system.
