The BBC has aired the British television series Dragon's Den since its launch.
The programme began on BBC Two in 2005 and became a prominent part of the broadcaster's factual entertainment schedule. Its format places entrepreneurs in front of a panel of investors, who assess proposed businesses and may offer money for a share of the company.
The BBC's version helped establish the word “dragon” as the British label for the investors. Other countries use related titles, including Shark Tank in the United States, but those programmes belong to separate national adaptations of the wider format. That difference can cause confusion when viewers compare episodes or investors across countries.
The programme's home is therefore the BBC, not a commercial UK network. BBC Two was the original channel associated with the series, although broadcaster scheduling and related programming can change over time. The BBC branding identifies the British version that began in 2005.
