The BBC produces and broadcasts the British entrepreneur-investment programme Dragon's Den.
The UK version began on BBC Two in 2005 and became a long-running part of the broadcaster's factual-entertainment schedule. Its format centres on entrepreneurs presenting businesses to a panel of investors in the hope of securing finance and expertise.
The programme is a British adaptation of an international format that originated in Japan. Because many countries have their own versions, the broadcaster can be confused with networks associated with adaptations elsewhere, including the American Shark Tank.
BBC is the concise canonical answer for the UK show. ITV, Channel 4 and Sky all operate major British television services, but they are not the broadcaster identified with the original British Dragon's Den series.
