The UK version of Dragons' Den first broadcast on BBC Two when the programme premiered in 2005.
The series brought entrepreneurs into a studio to pitch businesses and products to a panel of wealthy investors, known as the dragons. BBC Two was the channel used for the programme's original British run, establishing it as a factual-entertainment show aimed at a broad audience.
BBC Two is distinct from BBC One, the corporation's main general-interest channel, and BBC Three and BBC Four, which have had different programming roles. The show's format was adapted for Britain from a Japanese television concept and later became one of the BBC's best-known business programmes. Its channel history is also separate from international versions, which have been broadcast by different networks in their own countries.
