During the Second World War, growth and corporate generosity continued as IBM, which was founded in greater Binghamton, emerged as a global technology leader. Along with Edwin Link's invention of the flight simulator in Binghamton, IBM's growth helped transition the region to a high-tech economy. Other major manufacturers included Ansco and General Electric. Until the Cold War ended, the area never experienced an economic downfall, due in part to its defense-oriented industries. The city's population peaked at around 85,000 in the mid-1950s.
