This grid of radar and other sensors connected to central computers with over a million miles of telephone line. Its headquarters would later be located deep within the Colorado Cheyenne Mountains and be the model […]

How IT Came to Rule the World, 1.4: SAGE and Early Electronic Computing

The SAGE (Semi-Automatic Ground Environment) system conceived at MIT and built at IBM’s Poughkeepsie, New York facilities helped transform the computer from a bulky, slow, vacuum-tube switched numerical processor into a generalized, software-driven, transistor-enabled, media-enhanced computer with an accompanying communications system able to send digital data over telephone lines.
