Power 100 2018: Philip Almond, BBC

Almond has been betting on bigger and better data in his mission to "reinvent the BBC for a new generation". Launching a sign-in system for BBC iPlayer has helped create a database of 22 million registered users online. "We’re combining this personalised data – which represents about 10% of audiences’ time spent with the BBC across all platforms – with other sources, to give us a single view of how audiences use the BBC’s TV, radio and online services," he says.
