This is the first publication of AIJA's Antitrust Sub-Commission of the International Business Law Standing Commission. The book is the result of the reports from 20 different jurisdictions for the working session organized by the Antitrust Sub-Commission during the Annual Congress of AIJA in Sydney in September 1998. The reports were based upon a questionnaire prepared by the General Reporter and Editor and generally reflect legislation up until January 1999. The purpose of this book is to discuss the critical issues in applying antitrust laws to the media sector, having in mind three main issues, namely deregulation and convergence in the media industry worldwide, the effect of antitrust laws on the new media environment, and the balance between sector-specific regulation and antitrust rules.
