This book, Media Markets and Competition Law: Multinational Perspectives, published by Competition Policy International, in partnership with the Antitrust & Public Policy Review (formerly, Italian Antitrust Review), is a selection of 14 brief essays designed to provide a multinational perspective on the current state, and future, of competition law in media markets. This book builds on the contributions made for the Jevons Institute Colloquium on Future Perspectives on Media Markets, held in Rome on May 22, 2018. Whether it pertains to platform markets, crypto-currencies, or newspaper mergers, the reality is that antitrust enforcement has turned its collective eye towards the global economy's media markets. By highlighting the different regulatory approaches and various issues relating to the application of competition law to media markets in the United States, the European Union, and Australia, this book offers profound insights for practitioners and academics seeking to better understand the nature of competition in the evolving area of media markets. By providing a wide-spectrum of analysis, this book constitutes a useful tool to not only interpret, but to potentially predict, the current and forthcoming application and direction of competition law in media markets in the United States, the European Union, and other jurisdictions worldwide.
