Dragon's Den moved from BBC Two to BBC One.
The programme began on BBC Two in 2005, where it established its format of entrepreneurs pitching companies to wealthy investors. Its later move to BBC One reflected the show's growing popularity and gave it a larger mainstream television platform.
A channel move does not represent a change in the programme's basic premise. Entrepreneurs still seek investment by offering a percentage of their business, and the dragons can question, negotiate or decline the proposal.
This detail is sometimes confused with the show's original broadcaster because both BBC Two and BBC One have carried the series. The key distinction is chronological: BBC Two broadcast the launch, while BBC One became the later home of the established programme.
