The commonly accepted history of FM radio is one of the twentieth century’s iconic sagas of invention, heroism, and tragedy. Edwin Howard Armstrong created a system of wideband frequency-modulation radio in 1933. The Radio Corporation of America (RCA), convinced that Armstrong’s system threatened its AM empire, failed to develop the new technology and refused to pay Armstrong royalties. Armstrong sued the company at great personal cost. He died despondent, exhausted, and broke. But this account, according to Gary L. Frost, ignores the contributions of scores of other individuals who were involved in the decades-long struggle to realize the potential of FM radio. The first scholar to fully examine recently uncovered evidence from the Armstrong v. RCA lawsuit, Frost offers a thorough revision of the FM story. Frost’s balanced, contextualized approach provides a much-needed corrective to previous accounts. Navigating deftly through the details of a complicated story, he examines the motivations and interactions of the three communities most intimately involved in the development of the technology—Progressive-era amateur radio operators, RCA and Westinghouse engineers, and early FM broadcasters. In the process, Frost demonstrates the tension between competition and collaboration that goes hand in hand with the emergence and refinement of new technologies. Frost's study reconsiders both the social construction of FM radio and the process of technological evolution. Historians of technology, communication, and media will welcome this important reexamination of the canonic story of early FM radio.

In 1968 a team of scientists and engineers from RCA announced the creation of a new form of electronic display that relied upon an obscure set of materials known as liquid crystals. At a time when televisions utilized bulky cathode ray tubes to produce an image, these researchers demonstrated how liquid crystals could electronically control the passage of light. One day, they predicted, liquid crystal displays would find a home in clocks, calculators—and maybe even a television that could hang on the wall. Half a century later, RCA’s dreams have become a reality, and liquid crystals are the basis of a multibillion-dollar global industry. Yet the company responsible for producing the first LCDs was unable to capitalize upon its invention. In The TVs of Tomorrow, Benjamin Gross explains this contradiction by examining the history of flat-panel display research at RCA from the perspective of the chemists, physicists, electrical engineers, and technicians at the company’s central laboratory in Princeton, New Jersey. Drawing upon laboratory notebooks, internal reports, and interviews with key participants, Gross reconstructs the development of the LCD and situates it alongside other efforts to create a thin, lightweight replacement for the television picture tube. He shows how RCA researchers mobilized their technical expertise to secure support for their projects. He also highlights the challenges associated with the commercialization of liquid crystals at RCA and Optel—the RCA spin-off that ultimately manufactured the first LCD wristwatch. The TVs of Tomorrow is a detailed portrait of American innovation during the Cold War, which confirms that success in the electronics industry hinges upon input from both the laboratory and the boardroom.
