Simon Woodroffe left the original Dragon's Den investment panel in 2005.
Woodroffe was one of the original investors when the British programme launched. He was known for entrepreneurial ventures in hospitality and design, particularly the Yo! Sushi concept, which used conveyor-belt service to make the dining experience distinctive.
His time on the panel was brief compared with some other Dragons. Woodroffe departed during the programme's first year, and the investor lineup subsequently changed as the series developed its long-running format.
This date can be confused with the programme's launch year because both events occurred in 2005. The distinction is that the UK show premiered in 2005, while Woodroffe's departure also took place during that early period.
