The British television show Dragons' Den moved from BBC Two to BBC One in 2009.
The programme began on BBC Two in 2005 and later received a higher-profile network slot on BBC One. The move reflected the show’s established popularity and its importance within the BBC’s factual-entertainment schedule.
Changing channels did not change the central premise. Entrepreneurs still entered the den to pitch businesses, answer detailed questions and negotiate for investment from the Dragons. The move instead gave the established format access to a broader general audience.
The channel history is easy to mix up with the programme’s series chronology. Dragons' Den had already been running for several years before the move, and individual investor changes happened across the same period. The relevant distinction is that 2005 marks the British debut, while 2009 marks the switch from BBC Two to BBC One.
