The British television programme Dragons' Den is adapted from the Japanese reality show Money Tigers.
Money Tigers was created in Japan as a business-pitch programme in which entrepreneurs presented proposals to wealthy investors. The format was later adapted for television audiences in several countries, with each version retaining the central idea of negotiation over investment and ownership.
The British adaptation uses “dragons” as its name for the investors, while the American adaptation is known as Shark Tank. These programmes share the same broad international format but have different panels, presenters, broadcasters and local business cultures. Dragons' Den therefore is not an independently invented British format, even though its British panel and presentation style have made it a distinctive long-running programme.
