Whirlwind (computer)
The Whirlwind computer was developed at the Massachusetts Institute of Technology. It is the first computer that operated in real time, used video displays for output, and the first that was not simply an electronic replacement of older mechanical systems. Its development led directly to the United States Air Force's Semi-Automatic Ground Environment (SAGE) system, and indirectly to almost all business computers and minicomputers in the 1960s.
