Magpie Electricals
From Tardis Wiki, the free Doctor Who reference
Magpie Electricals was a radio and television shop located on Mafeking Terrace in London. In 1953 an alien called The Wire contacted the owner Mr Magpie, to help her get a physical body. (DW: The Idiot's Lantern)
Magpie Electricals apparently continues to exist. Martha Jones had a Magpie brand television in "The Sound of Drums", and a Magpie brand microphone can be seen in "Voyage of the Damned".
