Book excerpt: In this book, Lindsey A. Sherrill explores the exponential growth of true crime podcasting, including the role of the ubiquitous Serial podcast in the growth of the industry. Using both demographic population analysis and interviews with podcast hosts and producers, Sherill demonstrates that true crime podcasts exist as hybrid organizations, with diverse goals ranging from entertainment to criminal justice reform advocacy to journalistic inquiry. These competing motivations of podcast producers are explored, along with the ethical quandaries that emerge in the process of telling true crime stories. Sherrill traces true crime podcasting back to the infancy of the medium and examines the influences, innovations, and events that created the true crime podcast ecosystem, as well as its influence on real cases in the United States. Scholars of communication, sociology, and media studies will find this book of particular interest.
