The British television show Dragon's Den first premiered on BBC Two in 2005.
BBC Two launched the programme as a business reality series in which entrepreneurs sought investment from a panel of wealthy businesspeople. The channel became associated with the show's early years, including its original presenter and first investor lineup.
The programme later became a major BBC business-entertainment title, but it was not originally a BBC One production. BBC Two has traditionally carried factual, documentary and specialist programming, making it a natural home for a show centred on entrepreneurship and commercial decisions.
International versions may create confusion because the same format has different broadcasters and titles in different countries. The question refers specifically to the British series, whose initial home was BBC Two.
