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 contrast to its predecessor, which only showed promo videos, CD:UK was broadcast live on Saturday mornings with a studio audience and featured live performances, as well as star interviews and competitions. It also featured the Saturday Chart, which although was unofficial, usually reflected the new chart positions a day before the official chart was announced on Radio 1. This made the BBC's long-running Top of the Pops, which aired only the night before, seem very out-of-date broadcasting the previous week's chart. CD:UK later utilised an interactive chart based on viewers' votes, called the MiTracks Countdown. From 1999 to 2004, the show was sponsored by Tizer.
In 2002, the programmes was criticised for showing "raunchy" performances in a slot aimed at children, sparked by a performance of "Dirrty" by Christina Aguilera. In response, a spin-off programme entitled CD:UK Hotshots, featuring music videos which could be considered unsuitable for daytime viewing, was launched in January 2003 and broadcast overnight.
