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.
In 2017, when the Monks invaded the Earth, many citizens watched the Twelfth Doctor's broadcasts on them, such one about their fabricated role in human history, through the window of a Magpie Electricals shop. (TV: The Lie of the Land)TARDIS console room had Magpie Electricals brands on them. (TV: The Eleventh Hour) A power control device in the console room had Magpie's Electricals brand and was labelled Type V 310-A. (TV: Vincent and the Doctor)
- 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 (DOC: Call Me the Doctor) 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.
- Cover B of 9DO 1 by Will Brooks depicts several Magpie Electricals' branded mobile phones in the hands of aliens taking images of the Ninth Doctor.
