Unisys' history dates back to 1873 withE. Remington & Sons and the introduction of the first commercially viable typewriter to use theQWERTY keyboard layout.[4][5] Over a hundred years later, the company became known as Unisys in 1986 through the merger ofmainframe corporationsSperry andBurroughs, with Burroughs buying Sperry for $4.8 billion.[6]
The new company's name was chosen from over 31,000 submissions in an internal competition when Christian Machen submitted the word "Unisys", which was composed of parts of the words "united", "information", and "systems".[7]
The merger was the largest in the computer industry at the time and made Unisys the second-largest computer company with annual revenue of $10.5 billion.[8]W. Michael Blumenthal became CEO and Chairman.[9]
Soon after the merger, the market for proprietary mainframe-class systems, the mainstream product of Unisys and its competitors such asIBM, saw a decline[10] that continues, at a slower rate, today. Unisys responded by making the strategic decision to shift into high-end servers, including32-bit processorWindows Servers and information technology (IT) services, such as systems integration, outsourcing, and related technical services, while holding onto the profitable revenue stream from maintaining its installed base of proprietary mainframe hardware and applications.[10][11]
