Magpie Electricals

Magpie Electricals was originally a radio and television shop located on Mafeking Terrace in Muswell Hill. Despite the owner's death (TV: The Idiot's Lantern) the business managed to expand to several other locations, including stores in Stepney (AUDIO: Hunters of Earth) and on Starship UK in the 33rd century. (TV: The Beast Below)

History
In Essex in 1138, the Twelfth Doctor anachronistically played his electric guitar through a Magpie Electronics amplifier on a tank in a medieval castle. (TV: The Magician's Apprentice) He later used this same amplifier on the TARDIS. (TV: Before the Flood)

In 1953, the Wire contacted the owner, Mr Magpie, making him sell television sets cheaply as part of her plan to "tak[e] people's faces, their essences" and get a physical body. (TV: The Idiot's Lantern)

Although Magpie himself was killed by the Wire, Magpie Electricals survived the loss of its proprietor, and continued to exist well past the 1950s.

Behind the scenes

 * The use of the Magpie Electricals logo is something of an inside joke for Doctor Who's design team. It is on the back of the monitor on the Eleventh Doctor's TARDIS and included in the reconstructions of The Power of the Daleks and The Faceless Ones. It was also mentioned on the TARDIS tour on the Doctor Who BBC website.
