IBM and the BUNCH was the industry term for the main players in the computer industry during the heady days of the 1960s and 1970s. The BUNCH, who had emerged from the Seven Dwarves, were Burroughs, Univac, NCR, Control Data, and Honeywell. However, Honeywell was bought out by Bull, Univac merged with Sperry to form Sperry/Univac, which in 1984 merged with Burroughs to form Unisys, and in 1991 AT&T absorbed NCR. See Seven Dwarves, Dinosaur mating.
The group of mainframe computer competitors to IBM in the 1970s became known as the BUNCH: Burroughs, UNIVAC, NCR, Control Data Corporation, and Honeywell.
