BBC Two first broadcast the British business show Dragon's Den in 2005.
The programme premiered on 4 January 2005, bringing entrepreneurs before a panel of wealthy investors known as dragons. Contestants present a business idea or existing company and request investment in exchange for an ownership stake.
Dragon's Den is the British version of an international television format that originated in Japan. Its British run became one of the BBC's best-known factual-entertainment programmes, combining commercial negotiation with practical questions about sales, profit and valuation.
The first broadcast year is sometimes confused with the year the format was created in Japan, or with the launch year of another national version. For the British programme, the relevant date is 2005, when BBC Two began showing its own adaptation.
