Strictly Come Dancing (informally known as Strictly) is a British television dance contest in which celebrities partner with professional dancers to compete in mainly ballroom and Latin dance. Each couple is scored by a panel of judges. The format has been exported to over 40 other countries, licensed by BBC Worldwide, and led to a modern dance-themed spin-off Strictly Dance Fever. The Guinness World Records has named Strictly to be the world's most successful reality television format. The series is currently presented by Tess Daly and Claudia Winkleman.
The series has been broadcast on BBC One since 15 May 2004, typically on Saturday evenings with a following Sunday night results show. With its high viewing figures, Strictly Come Dancing has become a significant programme in British popular culture. Eleven stand-alone Christmas specials and nine charity specials have also been produced. Since the fourth series, the show has aired in high definition.
In April 2014, it was announced that Sir Bruce Forsyth would be retiring from presenting the main series. While intending to return as host for each Children in Need and Christmas special, he only did so for the Christmas special in 2014 and the Children in Need special in 2015. He sent a video message for the 2015 Christmas special as he was unable to appear due to illness. Forsyth died on 18 August 2017.
