several new divisions for defense, space exploration and other activities. The RCA Service Corporation provided large numbers of staff for the Distant Early Warning (DEW) Line. RCA units won five Army–Navy "E" Awards for Excellence in production. Due to the hostilities between Japan and the United States during World War II, the Victor Company of Japan became an independent company after seceding from RCA Victor in the United States; JVC retained the 'Victor' and "His Master's Voice" trademarks for use in Japan only. In 1955, RCA sold its Estate brand of large appliance operations to Whirlpool Corporation. As part of this transaction, Whirlpool was given the right to market "RCA Whirlpool" appliances through the mid-1960s. RCA manufactured equipment for repairing radios, such as oscilloscopes. RCA Graphic Systems Division (GSD) was an early supplier of electronics designed for the printing and publishing industries. It contracted with German company Rudolf Hell to market adaptations of the Digiset photocomposition system as the Videocomp, and a Laser Color Scanner. The Videocomp was supported by a Spectra computer that ran the Page-1 and, later the Page-II and FileComp composition systems. RCA later sold the Videocomp rights to Information International Inc.

Computers RCA was one of a number of companies in the 1960s that entered the mainframe computer field in order to challenge the market leader International Business Machines (IBM). Although at this time computers were almost universally used for routine data processing and scientific research, in 1964 Sarnoff, who prided himself as a visionary, predicted that "The computer will become the hub of a vast network of remote data stations and information banks feeding into the machine at a transmission rate of a billion or more bits of information a second ... Eventually, a global communications network handling voice, data and facsimile will instantly link man to machine—or machine to machine—by land, air, underwater, and space circuits. [The computer] will affect man's ways of thinking, his means of education, his relationship to his physical and social environment, and it will alter his ways of living. ... [Before the end
