Like so many facets of the modern world, television has been transformed by the application of digital technologies and the parallel and related development of the fast evolving Internet. While some broadcasters – especially those in developing economies – still utilise traditional analogue transmission techniques, most have transitioned to more efficient and powerful digital means of sending their programming to viewers. Use of digital technologies has enabled explosive growth in the number of channels and choices of programmes offered. It has also ceded more control to the viewer, allowing on – demand access to programming – not only from broadcasters and pay TV service providers, but also increasingly from online video services delivered over the open Internet. Indeed, as this report outlines, the definitional boundaries between broadcasting and other forms of digital video delivery are increasingly blurred.
