At the BBC, we spend a lot of time trying to understand and measure how media is consumed across the many screens in our audiences’ lives, from the big screens in our living rooms to the small screens in our hands. As a major media provider that delivers live and on-demand content online, there are seemingly endless questions that can be asked about the evolving habits of the BBC’s digital audiences. How many platforms, on average, do people use? What are the affinities between BBC brands and genres? Does the public appreciate what we do, and how can we measure that?
