The British TV show Dragons' Den first aired on BBC Two.
The programme launched on BBC Two in January 2005, giving British viewers a televised version of the entrepreneur-versus-investor format. Contestants pitch businesses or inventions, then negotiate with a panel of wealthy investors for a possible equity investment.
BBC Two is distinct from BBC One, the corporation's principal mainstream channel, and from commercial broadcasters such as ITV and Channel 4. That distinction matters because later international editions of the format have appeared on entirely different networks, which can create confusion in trivia questions.
The series' BBC Two identity is also reflected in its long-running association with factual entertainment and specialist programming. Although the dragons have changed over time, the broadcaster and the central pitch-room concept have been among the show's most recognisable constants.
