The UK television show Dragons' Den first broadcast on BBC Two.
The business reality programme premiered in 2005, with entrepreneurs presenting investment proposals to a panel of wealthy businesspeople known as the Dragons. BBC Two was the programme's original home, and the channel continued to carry the main series for many years.
The format was adapted from a Japanese programme called Money Tigers. In each pitch, entrepreneurs explain their business, request a specific investment, and offer a percentage of ownership. The Dragons can ask questions, negotiate, or decline to invest.
BBC Two is sometimes confused with BBC One because the series became a major mainstream hit and attracted a large audience. However, its original and principal British broadcast channel is BBC Two. The programme later became one of the BBC's best-known factual-entertainment formats, while international versions were produced in several countries.
