Referring back to the early 2000s, this book traces the development of podcasting from a “do-it-yourself” medium by amateurs into its current environment, where a wide variety of individuals, organizations, and platforms operate in an increasingly crowded and competitive market. Through original case studies of shows and platforms including "The Daily" and Spotify, the authors explore the processes and effects of commercialization, platformization, and datafication in the industry. Drawing on institutional theory and the growing body of scholarly literature about podcasting, they examine the shifts and reorientations in institutional logics that characterize podcasting and present the different types of actors that operate in the commercial and noncommercial podcast markets. The Institutional Development of Podcasting will be of interest to advanced students and researchers of audio media, journalism, and media industries.
