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. (TV: The Stolen Earth)
Behind the scenes Edit
Though the script for The Stolen Earth does not make clear it is Copper from Voyage of the Damned who started the foundation, Doctor Who: The Writer's Tale certainly does. However, that information is not valid so is not referenced in the main article above.
