Evan Davis hosted the British television programme Dragon's Den from its second series through series 18.
Davis presented the programme after its launch and remained its main host for many years. His role covered the entrepreneurs' introductions, the transitions between pitches and the closing explanations that helped viewers follow the negotiations.
The investor panel changed repeatedly during this period. Individual Dragons left, returned or were replaced, but the presenter provided continuity across those line-up changes. That is why the hosting run is longer than the tenure of many individual investors.
Davis is also known for serious BBC journalism, including work on Radio 4 and Newsnight. His Dragon's Den role was part of a broader broadcasting career, rather than his only television association. The series number is important because later presenters took over after his long run.
