Dragons' Den is the title of the BBC television programme that is the British version of the business-investment format.
The official British title uses the plural “Dragons” and places the apostrophe after the s. That punctuation reflects the programme's panel of several investors, who are collectively called the Dragons. The title is therefore commonly mistyped as “Dragon's Den,” with a singular possessive apostrophe.
The UK series premiered on BBC Two in 2005 and features entrepreneurs presenting businesses to investors. A successful pitch can lead to an offer of money for shares, although an offer made on camera may still require due diligence and final agreement.
The format has inspired or been adapted for broadcasters in many countries. The British title is also used for the specific BBC version, while related editions may use different local names, including Shark Tank in the United States.
