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.

When American radio broadcasting began in the early 1920s there was a consensus among middle-class opinion makers that the airwaves must never be used for advertising. Even the national advertising industry agreed that the miraculous new medium was destined for higher cultural purposes. And yet, within a decade American broadcasting had become commercialized and has remained so ever since. Much recent scholarship treats this unsought commercialization as a coup, imposed from above by mercenary corporations indifferent to higher public ideals. Such research has focused primarily on metropolitan stations operated by the likes of AT&T, Westinghouse, and General Electric. In American Babel, Clifford J. Doerksen provides a colorful alternative social history centered on an overlooked class of pioneer broadcaster—the independent radio stations. Doerksen reveals that these "little" stations often commanded large and loyal working-class audiences who did not share the middle-class aversion to broadcast advertising. In urban settings, the independent stations broadcast jazz and burlesque entertainment and plugged popular songs for Tin Pan Alley publishers. In the countryside, independent stations known as "farmer stations" broadcast "hillbilly music" and old-time religion. All were unabashed in their promotional practices and paved the way toward commercialization with their innovations in programming, on-air style, advertising methods, and direct appeal to target audiences. Corporate broadcasters, who aspired to cultural gentility, were initially hostile to the populist style of the independents but ultimately followed suit in the 1930s. Drawing on a rich array of archives and contemporary print sources, each chapter of American Babel looks at a particular station and the personalities behind the microphone. Doerksen presents this group of independents as an intensely colorful, perpetually interesting lot and weaves their stories into an expansive social and cultural narrative to explain more fully the rise of the commercial network system of the 1930s.

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.
