New technologies, whether text message or telegraph, inevitably raise questions about emotion. New forms of communication bring with them both fear and hope, on one hand allowing us deeper emotional connections and the ability to forge global communities, while on the other prompting anxieties about isolation and over-stimulation. Feeling Mediated investigates the larger context of such concerns, considering both how media technologies intersect with our emotional lives and how our ideas about these intersections influence how we think about and experience emotion and technology themselves. Drawing on extensive archival research, Brenton J. Malin explores the historical roots of much of our recent understanding of mediated feelings, showing how earlier ideas about the telegraph, phonograph, radio, motion pictures, and other once-new technologies continue to inform our contemporary thinking. With insightful analysis, Feeling Mediated explores a series of fascinating arguments about technology and emotion that became especially heated during the early 20th century. These debates, which carried forward and transformed earlier discussions of technology and emotion, culminated in a set of ideas that became institutionalized in the structures of American media production, advertising, social research, and policy, leaving a lasting impact on our everyday lives.
