Mediatization is of the most successful yet most often discussed approaches used in media and communication studies. The issues of media change and societal change are central in this respect, with two traditions having developed, which examine the role of the media in our modern society in different ways (qualitative v quantitative methods). The research focus could be divided between a) changes to communication in humans’ daily lives, for example through smartphones, and b) influences of the mass media in different areas of society such as politics, the economy and sport. The second edition of this book, which has been revised and updated, explains the origins of these approaches, presents key studies and findings on them and discusses their similarities and differences.
