In common with most media and consumer technologies, radio is migrating from analogue to digital operation. Europe was the first region of the world to develop a digital replacement for traditional analogue broadcast radio. The Digital Audio Broadcasting (DAB) project began in 1987 and the first domestic DAB broadcasts began in 1995. However, DAB has made less progress than originally anticipated: some countries are at a relatively advanced level of development while others have not begun significant DAB services. This article examines the development of the DAB service in four European countries, illustrating the variability in modes of development. The different digital policies adopted by each country are key factors in these developments and we show how the existing state of analogue radio and the limitations of the technical system have shaped these policies.

Digital audio broadcasting is a major innovation in radio, one that is at its most advanced in Europe. It has the potential to deliver high-quality audio reception and to increase significantly the capacity of the radio spectrum, with the possibility of an expansion of both the range and diversity of radio programming. Nevertheless, in the UK and elsewhere it remains relatively unknown and under-adopted in comparison with other consumer technologies like digital television. This article examines the origins of digital radio, and considers how this technology is expected to become a mass communications technology, eventually supplanting analogue radio. However, in its present form, there is little that is novel currently being offered on digital radio, and the economic and political contexts in which it is being developed may encourage further concentration of ownership and reduce diversity of choice in listening. Unlike previous innovations then, such as FM broadcasting, there appear to be few compelling advantages of digital radio that will persuade listeners to adopt this new technology. If this new technological system is to succeed, alternative uses must be found for it, and one area for which it might be suited is mobile data communications. The article concludes by suggesting that this might mean that radio becomes of secondary importance to this potentially lucrative application of digital audio broadcasting technology.
