Five Dragons sat on the panel when the British series Dragon's Den launched in 2005.
The original line-up consisted of Peter Jones, Duncan Bannatyne, Rachel Elnaugh, Theo Paphitis and Simon Woodroffe. Each investor brought a different business background, giving the panel a mixture of expertise in technology, retail, leisure, property and consumer products.
The number of Dragons later varied as the programme changed its panel. Guest investors and replacements appeared in different series, so viewers familiar with a later line-up may remember a different number or combination of investors.
The five-person original panel is a historical fact about the launch, not a rule that every later episode had to follow. The format's drama comes from entrepreneurs trying to persuade one or more individual investors, rather than from a fixed team structure.
