Control Data Corporation is a developer of high-speed computers used heavily in government and scientific installations. CDC was one of the nine major United States computer companies through most of the 1960s. For most of the 1960s, Seymour Cray worked at CDC and developed a series of machines that were the fastest computers in the world by far. CDC only lost that title in the 1970s after Cray left the company to found Cray Research (CRI). After several years of losses in the early 1980s, CDC made the decision to leave the computer manufacturing business and sell those parts of the company in 1988, a process that was completed in 1992 with the creation of Control Data Systems, Inc. The remaining businesses of CDC currently operate as Ceridian.
