Edison Industries

Edison Industries is a technology corporation created by John Dee under the guise of Thomas Edison, as a way to make himself lots of money. Because Dee is an Immortal and is thought to be dead by the mundane world, it operates through several subsidiaries.

History
Founded in 1934 to manage Dee's various companies after "Edison's" death, Edison Industries began to innovate and manufacture technologies in aviation, communications, current, digital devices, energy production, global research, healthcare, lighting, mining, oil and gas, power, renewable energy, and transportation. Most of its work has been done through General Electric and its subsidiaries, becoming one of the most successful of Dee's companies.
