Control Data Corporation (CDC), was one of the pioneering supercomputer firms. For most of the 1960s they built the fastest computers in the world by far, only losing that crown in the 1970s to what was effectively a spinoff. CDC was one of the eight major computer companies through most of the 1960s; along with CDC these were IBM, Burroughs Corporation, NCR, General Electric, Honeywell, RCA, and UNIVAC. CDC was well known and highly regarded throughout the industry at one time, but today is largely forgotten.
