In the BBC business show Dragon's Den, on what date did the first episode premiere?

The first episode of the BBC business show Dragon's Den premiered on 4 February 2005.

The British programme is based on the Japanese format Money Tigers and was developed for the BBC as a television pitch show. Entrepreneurs present business ideas to a panel of wealthy investors, known as Dragons, and seek investment in return for equity in their companies.

The programme became part of BBC Two's factual-entertainment schedule and later moved to BBC One. Its format helped popularise televised business pitching in the United Kingdom, while local versions were produced in many other countries.

The date is sometimes confused with the show's production or announcement dates. The relevant milestone is the broadcast of the first UK episode, rather than the launch of the Japanese original or the premiere of an international adaptation.
