The early twentieth century witnessed a profound transformation in the history of modern sound media, as professional radio workers developed production practices and performance styles for broadcasting during the 1920s, its initial decade of expansion in the United States. Mapping the programming forms pursued by early writers and programmers, production techniques adopted by studio engineers, and performance styles cultivated by on-air talent, Making Radio shows how workers within this burgeoning industry negotiated pressures from regulators, station owners, sponsors, and critics to develop defining sets of craft practices for one of the century's most influential studio arts. Radio workers' struggles to institutionalize standards of professional practice and win broader cultural acceptance for their medium, the book argues, secured broadcasting's place in American culture and established key precedents for neighboring film and record industries that guided their own conversions to electric sound. Making Radio reveals radio as the missing link in the history of modern sound culture, showing how radio workers shaped listening sensibilities for a new era of electric sound entertainment.
