Control Data Corporation (CDC)

Control Data Corporation (CDC) was a supercomputer firm. 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). CDC was one of the nine major United States computer companies through most of the 1960s; the others were IBM, Burroughs Corporation, DEC, NCR, General Electric, Honeywell, RCA, and UNIVAC. CDC was well known and highly regarded throughout the industry at one time.
