Dragon's Den production moved to MediaCityUK in 2012 after filming at Pinewood Studios.
MediaCityUK is a mixed-use media development in Salford, Greater Manchester. The BBC became a major presence there, and the move placed production within one of Britain's most important broadcasting hubs outside London.
Earlier series had been filmed at Pinewood Studios in Buckinghamshire. The relocation did not change the programme's premise: entrepreneurs still pitch to a panel of investors and negotiate for equity. It changed the production base and reflects the BBC's wider expansion of operations in Salford.
MediaCityUK is sometimes described simply as Manchester because it is part of the Greater Manchester area, but its precise location is Salford. Cardiff Bay and the former BBC Television Centre are associated with other television production activity, not this 2012 Dragon's Den move.
