The BBC originally commissioned the UK version of Dragon's Den.
The programme was launched as a BBC Two series, adapting the Japanese business format for British viewers. The BBC commissioning decision established the UK version that later became one of the broadcaster's best-known factual-entertainment programmes.
The show is sometimes associated with other commercial channels because international versions and rival investment programmes have appeared on different networks. Those versions should not be confused with the British series, whose home is the BBC.
BBC Two is a specific channel within the BBC, while BBC is the broadcasting organisation. The most precise answer to which broadcaster commissioned and broadcasts the British version is therefore BBC, rather than a competing UK network or an overseas franchise.
