Dragons' Den moved to BBC One when its regular broadcast shifted from BBC Two.
The British series began on BBC Two in 2005, but its later popularity led the BBC to move it to BBC One. This change placed the programme on the corporation's principal general-entertainment channel and reflected its growing audience and status within the BBC schedule.
A channel move does not mark the creation of a new version of the programme. The British series, its pitch structure, and its investment-panel concept continued across the change. Viewers may also confuse the main series with companion programming and special episodes, which can have different scheduling arrangements.
The move illustrates how a factual entertainment programme can develop from a specialist channel launch into a mainstream television property. Despite changes in investors and presenters, the show has retained its central format: entrepreneurs seek funding by offering equity in their businesses.
