Digital innovation not only has a great impact on the market structure of telecommunications and broadcasting, but it also changes their size and scope. In particular they are converging at high speed and creating new markets on an international scale. The convergence of telecommunications and broadcasting raises many questions. What form will convergence take in the future? When convergence produces new opportunities in the information, education and entertainment markets, what sort of rules of the game will be required? How will the players behave in these new markets? What policies might be needed? This international comparative study arises from a recent conference held at Waseda University (Tokyo) and contains up to the minute contributions by economists, political scientists and engineers from Japan, United Kingdom and Germany. It will be essential reading for business and investment managers, policy makers and researchers.
