Dragon's Den originally launched in Britain on BBC Two.
The programme became a notable BBC Two factual-entertainment series, combining business advice, negotiation and reality television. Its format places entrepreneurs in front of a panel of investors, who judge whether the proposal is commercially attractive and whether the requested valuation is reasonable.
BBC Two has traditionally carried factual, documentary and specialist entertainment programming, making it a natural home for a show centred on business pitches. The series later became one of the BBC's best-known recurring formats and remained associated with the channel in public discussions of British television.
Viewers sometimes confuse the programme's channel with BBC One because of its broad popularity. However, the show's original home was BBC Two, not BBC One or a commercial broadcaster such as ITV or Channel 4.
