Teddington Studios are specifically television production facilities located in Teddington in the London borough of Richmond-upon-Thames. They were bought by Pinewood/Shepperton prior to their first, and as of 2008, only use by Doctor Who.
Minor work was done for Army of Ghosts at Teddington because those were the studios at which Trisha Goddard taped her real-life talk show. An insert of Trisha is seen as the Tenth Doctor flips through channels on the television to try to understand Britain's newfound obsession with ghosts. The insert was recorded at Teddington after a taping of her regular broadcast.
