Strictly Come Dancing (informally known as Strictly) is a British television show, featuring celebrities with professional dance partners competing in a Ballroom and Latin dance competition. Each couple will be scored out of 10 (with all four judges 40). The judges: Craig Revel Horwood, Len Goodman, Arlene Phillips (series 1 to 6), Alesha Dixon (Series 7 to 9), Darcey Bussell and Bruno Tonioli. The title of the show suggests a continuation of the long-running series Come Dancing, with an allusion to the film Strictly Ballroom. The format has been exported to over 40 other countries (see Dancing with the Stars), and has also inspired a modern-dance themed spin-off Strictly Dance Fever. The show is currently presented by Tess Daly and Claudia Winkleman, with former presenter Sir Bruce Forsyth continuing to front special episodes.
The show has run on BBC One since 15 May 2004, primarily on Saturday evenings with a following Sunday night results show (with certain exceptions). The twelfth series ended on 20 December 2014 and a further eleven stand-alone Christmas specials have also been produced, in consecutive years from 2004 to 2014. Nine charity specials have also been produced since 2008. Since the fourth series, the show has also been aired in high definition on BBC HD, and BBC One HD from series 8.
