This book is written by media scholars from all over Europe who are members of the Euromedia Research Group. What unites the group is the joint interest of its members in the analysis of media structures and media policy in Europe against the background of contemporary communication theories and concepts. The book has two parts: First, it looks into structural changes in specific media formats such as newspapers, radio, television and online-media. Second, it analyses specific problems and challenges in a comparative way, such as the creation of public sphere(s), the relation between media and democracy, public service media, media regulation and media governance, challenges of media industries etc. The book addresses graduate students in mass communication, scholars and practitioners interested in reflecting main development trends. It follows up from four books written by the Euromedia Research Group on media policy, published in 1986, 1992, 1999 and 2007.
