Peter Jones, the Dragon's Den investor associated with Phones International Group, is an entrepreneur.
Jones is a British businessman and television personality. His business career has included interests in telecommunications, technology, leisure and other consumer-facing sectors, which inform the commercial questions he asks entrepreneurs on Dragon's Den.
Phones International Group was founded by Jones and became part of his wider business history. He is often described in biographies as an entrepreneur and investor rather than being defined solely by his television role.
The alternatives describe unrelated occupations. Jones has appeared in television programmes, but he is not principally a film director; he is not known as a professional athlete or novelist. On Dragon's Den, his function is that of an investor, while his broader professional description is entrepreneur.
