In the BBC television show Dragon's Den, on what date did the UK series first premiere?

The BBC television show Dragon's Den first premiered in the UK on 4 January 2005.

The programme was adapted for British television from the Japanese business reality format Money Tigers. It gives entrepreneurs a short presentation opportunity before a panel of wealthy investors, who may offer capital in exchange for an ownership stake.

Dragon's Den became part of the BBC's factual-entertainment schedule and helped popularise televised business pitching in Britain. The UK version has since produced numerous spin-offs, catchphrases and widely discussed negotiations.

The premiere date is sometimes confused with the launch dates of international versions. Dragon's Den is a British adaptation, while other countries use titles such as Shark Tank or Lions' Den for related formats.
