The BBC has aired the UK television show Dragon's Den since its 2005 debut.
Dragon's Den is the British adaptation of the international Dragons' Den format, in which entrepreneurs present businesses to wealthy investors. The BBC version first appeared on BBC Two in 2005 and became one of the channel's best-known factual entertainment programmes.
The programme is associated with the BBC rather than a commercial broadcaster, although its format has been adapted in many countries by different networks. The title is also written with an apostrophe in the British version: Dragon's Den.
A common mix-up is confusing the BBC programme with Shark Tank, the separate American adaptation of the same broad investment-pitch concept. The BBC series has its own investors, presenters, series history and UK business setting.
