The British version of Dragon's Den is broadcast on BBC One.
The programme began on BBC Two in 2005 before moving to BBC One in 2009. This channel change reflected the show's growing popularity and gave it a prominent place in the BBC's mainstream evening schedule. The format remained focused on entrepreneurs presenting businesses to investor panelists.
The move can cause confusion because early series are associated with BBC Two, while later episodes are associated with BBC One. Both channels are part of the BBC, but they represent different stages in the programme's broadcast history. The answer therefore refers to the channel carrying the established modern series, not the channel used at launch.
Dragon's Den is a BBC production rather than an ITV or Channel 4 programme. Its international versions may appear on different broadcasters and may use different titles, but the British edition has remained a BBC property. The show's familiar pitch room, negotiation scenes and panel changes continued after the move.
