Dragon's Den moved from BBC Two to BBC One in 2021.
The programme had been a BBC Two fixture since its British launch in 2005. Its transfer to BBC One accompanied the nineteenth series and reflected the show's established popularity with a broad audience.
The move happened during a period of significant panel and production attention. Steven Bartlett joined the Dragons for series 19, becoming the youngest investor in the programme's British history at that point. The BBC continued to present the same core pitch-and-investment format after the channel change.
Some viewers associate the move with later series because the programme has continued to evolve and repeat episodes across BBC services. The key date is 2021: that is the year of the main channel transfer, not the year the British programme first appeared or the year its Japanese source began.
