IBM Computer The Story of SAGE DVD (1957)

SAGE, the Semi Automatic Ground Environment, was an automated control system used by NORAD for collecting, tracking and intercepting enemy bomber aircraft from the late 1950s into the 1980s. In later versions, the system could automatically direct aircraft to an interception by sending commands directly to the aircraft's autopilot.  By the time it was fully operational the Soviet bomber threat had been replaced by the Soviet missile threat, for which SAGE was entirely inadequate. Nevertheless, SAGE was tremendously important; it led to huge advances in online systems and interactive computing, real-time computing, and data communications using modems. It is generally considered to be one of the most advanced and successful large computer systems ever developed.  IBM's role in SAGE (the design and manufacture of the AN/FSQ-7 computer, a vacuum tube computer with ferrite core memory based on the Whirlwind II) was an important factor leading to IBM's domination of the computer industry.
