The British TV series Dragon's Den first premiered in 2005 on BBC Two.
The programme debuted on 4 January 2005, bringing entrepreneurs before a panel of wealthy investors known as Dragons. Contestants present a business idea and request money in exchange for a percentage of ownership.
Dragon's Den is the UK version of a format that originated in Japan. Its launch helped establish business-pitch television as a recurring genre in Britain, later inspiring international adaptations and spin-offs.
The year is sometimes confused with 2004 because the Japanese format had already existed and the British production was announced before its broadcast. The UK series itself began in January 2005, making that the canonical premiere year.
