IBM was the largest of the eight major computer companies (with UNIVAC, Burroughs, NCR, Control Data Corporation, General Electric, RCA and Honeywell) through most of the 1960s. People in this business would talk jokingly of "IBM and the seven dwarfs," given the much smaller size of the other companies' computer divisions (IBM produced approximately 70% of all computers in 1964).^[11]

The major technical development of the 1960s was IBM's System/360 series.^[12]
