Peter Jones remained on the British programme Dragons' Den from its first series through series 20.
Jones was part of the original British panel when Dragons' Den premiered in 2005, and he continued as a Dragon through the twentieth series. His business interests have included technology, media, telecommunications, property, and retail. That broad experience has made him one of the programme's most recognisable long-term investors.
The panel changed substantially across the show's run. Original Dragons such as Duncan Bannatyne and Theo Paphitis later left, while investors including Deborah Meaden, Touker Suleyman, Sara Davies, and Steven Bartlett joined in different periods. Jones's continuous presence distinguishes him from Dragons who returned for special appearances or served for only a few series.
The wording “original Dragon” can be misunderstood as meaning the first investor to appear in an episode. It means a member of the initial British panel. Jones was not the only person in the original lineup, but he was the original Dragon who remained on the programme across its first twenty series.
