Three inheritances arrived at the 1955 merger, and each outlived the corporation that held them. From Eckert and Mauchly came the machine that first persuaded a mass audience that a computer could draw a conclusion: the 1952 election-night forecast broadcast on CBS, produced from a partial sample and initially withheld because the network did not believe it. From Engineering Research Associates came the scientific line whose 1956 revision is generally credited with the first hardware program interrupt, a mechanism letting an external event halt the running programme and force the processor to attend to something else. Interactive and time-shared computing, without which the AI laboratories of the 1960s could not have worked as they did, rests on that idea. The third inheritance was Grace Hopper, who spent these years insisting that a machine could translate English-like statements into its own instructions; FLOW-MATIC ran on the company's hardware before feeding into COBOL, and the objection it had to overcome — that programming was intellectual work only people could perform — was the objection AI would meet in a larger form. Two losses count as well. William Norris and Seymour Cray both departed for Control Data in 1957, seeding the American supercomputer industry, and in 1973 a federal court invalidated the ENIAC patent the company had been licensing, leaving the general-purpose digital computer unowned by anyone.
