Peter Jones became the first person to appear in every series of the programme, serving as the British Dragon's Den panel's constant investor.
Jones has been present since the series began in 2005. His continued participation distinguishes him from investors whose tenures covered only particular periods, including the original Dragons who later left the show.
As an investor, Jones listens to pitches, questions entrepreneurs about revenue and valuation, and may offer money in return for an agreed share of the business. His business interests have included technology, media and telecommunications, sectors that frequently feature in the programme's pitches.
The wording refers to every series of the British programme. It should not be confused with appearing in every episode, making the most deals or investing the largest total amount; those are separate claims.
