In the British TV series Dragons' Den, on what date was the first episode broadcast?

The first episode of the British TV series Dragons' Den was broadcast on 4 January 2005.

The programme brought entrepreneurs into a room to present business ideas to a panel of wealthy investors, known as dragons. Contestants sought investment in exchange for a percentage of their company, making the negotiation itself a central part of the entertainment.

Dragons' Den is the British adaptation of a Japanese television format. The UK version became one of the BBC's best-known factual entertainment programmes and later inspired versions in several other countries.

The launch date is sometimes confused with the year the format arrived in Britain or with dates associated with later series. The relevant date is the broadcast of the first British episode, not the creation of the original Japanese format.
