The British version of Dragon's Den first premiered on BBC Two in 2005.
The programme debuted on 4 January 2005, bringing entrepreneurs into a studio to pitch for investment from a panel of wealthy businesspeople, known as the Dragons. Contestants generally offer a percentage of their company in exchange for money, expertise, or both.
The British series is part of an international franchise. Its format was adapted from the Japanese television programme Money Tigers, and the British version later became one of the best-known editions worldwide. Although the panel and presenter have changed repeatedly, the central pitch-and-negotiation structure has remained consistent.
A common mix-up is confusing the British premiere with the launch dates of other versions, including the Canadian and American adaptations. The BBC programme also moved between scheduling arrangements over the years, but its first broadcast year remains 2005.
