As the BBC's popular business show continues its 2023 series, some might be wondering how long Dragons' Den has been on UK television screens.

The show, which is now an international brand, originally started in Japan before being picked up by BBC controllers.

Dragons' Den has seen huge changes over its run with the dragons and the show's locations constantly evolving.

How long has Dragons' Den been on television?

Dragons' Den first aired via the BBC on January 4, 2005, meaning the popular format has been going strong for over 18 years.

The show has seen 19 series, with it being on its 20th as of the time of writing.

In that time, Dragons' Den has changed remarkably.
