He has taught media history, theory, and criticism at the University of Wisconsin–Madison and Washington University in St. Louis. His book, Television in the Age of Radio: Modernity, Imagination, and the Making of a Medium (Rutgers University Press, 2014), demonstrates how evaluative frameworks and circuits of cultural authority shaped both the emergence of television and the ways that thinking and talking about electronic images became an index of modernity. His research interests include the media industries’ business and legal cultures, media technologies, the mediation of masculinities, and the history of debates about the future of television.
