Itek

Itek Corporation was a United States defense contractor that initially specialized in camera systems for spy satellites and various other reconnaissance systems.^[1] In the early 1960s they built a conglomerate in a fashion similar to LTV or Litton, during which time they developed the first CAD system and explored optical disc technology. These efforts were unsuccessful, and the company shed divisions to various companies, returning to its roots in the reconnaissance market. The remaining portions were eventually purchased by Litton in 1983, and then Hughes, Raytheon, and Goodrich Corporation.
