The Great Intelligence Institute was an organisation created by the BBC in 2012 for Doctor Who.
The Great Intelligence Institute was founded in London, Great Britain during the 19th century by Walter Simeon. It was established with the goal of creating a physical form for the Great Intelligence. The Institute manipulated snow so that it could be imbued with the Great Intelligence's essence. It took the institute decades to achieve its goal, resulting in the rising of snowmen on Christmas Eve, 1892 which the Doctor put an end to.
