In this chapter, the impact of technological transformations on public service broadcasters is analysed and systematised. Particular attention will be paid to (1) digitalisation and analogue–digital switchover of broadcasting, (2) enhancement of image technology: introduction of high-definition (HDTV) and three-dimensional television (3D TV), (3) evolution of online strategies: from the Web to a multiplatform online context. These innovation vectors imply the existence of similar changes in the structure, operational logics, and business models of television systems across Europe, having, however, different timings and intensities in each national market. In addition, they also affect the way in which users access and consume media. Overall, they create a broad and diverse range of challenges, opportunities, and risks for the players involved.
