Revolution in the Echo Chamber is a sociohistorical analysis of British and American radio and audio drama from 1919 to present day. This volume examines the aesthetic, cultural, and technical elements of audio drama along with its context within the literary canon. In addition to the form and development of aural drama, Leslie Grace McMurtry provides an exploration of mental imagery generation in relation to its reception and production. Building on historical analysis, Revolution in the Echo Chamber provides contemporary perspective, drawing on trends from the current audio drama environment to analyze how people listen to audio drama, including podcast drama, today--and how they might listen in the future.
