CD:UK (CountDown:United Kingdom), stylised as cd:uk, was a British music television programme. Originally run in conjunction with SMTV Live, the programme first aired on ITV on 29 August 1998 to rival the BBC's Live & Kicking and was the replacement for The Chart Show, which had been airing on the network for nine and a half years. In its first seven and a half years, CD:UK had become one of the most important music programmes on British television, but by 2006, its future looked uncertain.
