Strictly Come Dancing is a British dance contest show 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 title of the show is an amalgamation of 1992 film Strictly Ballroom and long-running TV series Come Dancing. The format has been exported to 60 other countries under the title Dancing with the Stars, licensed by BBC Worldwide, and led to a modern dance-themed spin-off Strictly Dance Fever. The Guinness World Records named Strictly as the world's most successful reality television format in 2010.
