Millingdale website

The ice cream company Millingdale had a website in the Doctor's universe and Pete's World. The website was linked to by henriksonline.co.uk, to a description of the Henrik's Surprise flavour.

The readers of Defending the Earth! from the Doctor's universe went to the Millingdale website to look for "the secret of Henrik's surprise", finding the secret password "Gemini12" in the description of their ice cream flavour Henrik's Surprise. The readers' correspondant, "ChatGuest1", also had prior knowledge of Millingdale. (GAME: Cybus Spy)

Behind the scenes
The Millingdale company originated from the tie-in website Millingdale, one of many websites created by the BBC in 2006 to promote series two of Doctor Who. However, the world building of the site is complex due to its relationship to other contemporary websites at the time; fiction on the site, such as Our Flavours, references both the Doctor's universe and Pete's World without distinction or explanation, meaning that a website that exists in the Doctor's universe makes mention of Henrik & Son, a company that only exists in Pete's World (its counterpart is Henrik's Department Store) and vice versa.
