Peter Jones became a Dragon on every series of the British programme Dragon's Den from its 2005 launch.
Jones is a British entrepreneur and businessman whose interests have included technology, media, retail and property. On the programme, he became known for questioning entrepreneurs about sales, margins, valuation and the practical details behind their proposals.
The original investor panel also included Duncan Bannatyne, Rachel Elnaugh, Theo Paphitis and Doug Richard. Unlike Jones, several of those original Dragons later left the programme, and the panel changed repeatedly across subsequent series.
“Every series” refers to his continuous participation in the UK programme, not to every international version of the format. Jones is also associated with other television business programmes, but Dragon's Den made him widely recognised as one of Britain's best-known TV investors.
