Peter Jones was the original Dragon who remained on Dragon's Den continuously for many series.
Jones joined the programme at its British launch and became one of its most recognisable investors. His business interests include technology, telecommunications, media, and consumer products, so his questions often focus on sales potential, margins, intellectual property, and the entrepreneur's ability to scale.
The original panel included Peter Jones, Duncan Bannatyne, Rachel Elnaugh, Simon Woodroffe, and Doug Richard. Unlike several of those investors, Jones continued as a regular Dragon across the programme's long run. That continuity made him a visual and historical link between the earliest BBC episodes and later line-ups.
The wording can cause confusion because “original investor” means a member of the first panel, not necessarily the first investor to make an offer in a particular episode. It also does not mean Jones invested in every business pitched on the show.
