International Electromatics

International Electromatics was a company founded by Tobias Vaughn on Earth. Packer was head of security there. It was at one point the world's largest manufacturer of electronic equipment; their micro-monolithic circuits were present in almost every piece of electronic equipment sold.

When the Cybermen planned their invasion of Earth, they struck a deal with Vaughn: that the world was to be put under Cyber control, through the micro-monolithic circuits, and then Vaughn would become the ruler of Earth. (TV: The Invasion)

The company was shut down after the incident. However, Professor Ralph Cornish revitalised the British Rocket Group with technology from International Electromatics. (PROSE: Who Killed Kennedy)
