Mr Copper Foundation

The Mr Copper Foundation was a foundation that developed the Subwave network. Harriet Jones used this technology to communicate with Martha Jones, Torchwood Three and Sarah Jane Smith. (DW: The Stolen Earth)

Behind the scenes
Presumably, it was founded by Mr. Balydon Copper, an Earthonomics "expert" and tour guide aboard the Spaceship Titanic. The Doctor left him on Earth with £1 million he had placed on his tour guide credit card at the end of "Voyage of the Damned," and he no doubt used a portion of these monies to fund the "Mr Copper Foundation."
