BBC HD

Background
BBC HD was a high-definition television channel provided by the BBC. The service was initially run as a trial from May 15, 2006 until becoming a full service on December 1, 2007. It broadcast only during the afternoon and evening and only broadcast programming shot in high definition, either in a simulcast with another channel or by inserting a repeat of an HD programme. BBC HD closed on March 26, 2013 and was replaced by an HD simulcast of BBC Two, partly as a result of budget cuts affecting the BBC.
