This book focuses on key challenges related to conducting research on mediatisation, presenting the most current theoretical, empirical, and methodological challenges and problems, addressing ignored and less frequently discussed topics, critical and controversial themes, and defining niches and directions of development in mediatisation. With a focus on the under-representation of certain topics and aspects, as well as methodological, technological, and ethical dilemmas, the chapters consider the main critical objections formulated against mediatisation studies and exchange critical positions. Moving beyond areas of common focus - culture, sport, and religion - to emerging areas of study such as fashion, the military, business, and the environment, the book then offers a critical assessment of the transformation of fields and the relevance of new and dynamic (meta)processes including datafication, counter-mediatisation, and platformisation. Charting new paths of development in mediatisation, this book will be of interest to scholars and students of mediatisation, media studies, media literacy, communication studies, and research methods.
