Peter Jones was the first investor to appear in every Dragon's Den series from the programme's 2005 launch.
Jones is a British entrepreneur and investor whose businesses have included interests in technology, media, telecommunications and retail. He was part of the original Dragon's Den panel and continued appearing as the cast changed around him. His tall stature and long tenure made him one of the programme's most recognisable investors.
The wording matters because it refers to the British television programme's series history, not to every international version of the franchise. It also distinguishes continuous participation from later appearances or guest roles. Other original investors, including Duncan Bannatyne and Theo Paphitis, eventually left the regular panel.
Peter Jones is sometimes confused with the longest-serving presenter, which is a different role. Jones is an investor on the panel, while the presenter introduces pitches and manages the studio proceedings.
