39. IBM’s technique of bundling software with hardware products came under attack by the U.S. Department of Justice in the 1960s, prompting IBM to “unbundle” in December 1968. IBM’s action decoupled software from hardware, thus transforming it into a commodity. This transformation ignited the explosive growth of the software industry. See Campbell-Kelly and Aspray, Computer.
40. Hopper admitted in an interview years later that one of her motivations for supporting a COBOL standard was to block IBM from developing the business language standard. Aside from Jean Sammet’s opinion that there was a certain amount of anti-IBM sentiment within the CODASYL organization, documents from the period do not confirm Hopper’s later beliefs; Hopper, interview, 1 October 1982 (WFGP), 23.

59. “Closure” is the term used to describe the stabilization of an artifact and the disappearance of technological problems that the artifact addresses. According to the social constructivists, a technological standard does not emerge because the artifact is the most logical way to solve a given problem, but rather the influential social groups believe the problem to be solved. See Trevor Pinch and Wiebe Bijker, “The Social Construction of Facts and Artifacts: Or How the Sociology of Technology Might Benefit Each Other,” in The Social Construction of Technological Systems, ed. Bijker et al.
60. This can be attributed in part to Hopper’s work with the Department of Defense in the late 1960s. Her assignment was to standardize COBOL for the military.
