The British television programme Dragons' Den is broadcast by the BBC.
The series began on BBC Two in 2005 and became a long-running part of the BBC's factual entertainment programming. Entrepreneurs pitch businesses to investors, commonly seeking money in exchange for a percentage of ownership. The programme combines business discussion with competitive television drama.
BBC Two was the original home of the series, although BBC scheduling and programme branding have changed over the programme's long run. The broadcaster is often identified simply as the BBC, the United Kingdom's public-service broadcasting organisation.
This answer refers to the UK version specifically. Other countries have produced their own adaptations, sometimes under the Dragons' Den name and sometimes under titles such as Shark Tank. Those versions belong to different broadcasters and have different investor panels.
