We all love stories. But why do we tell them? And why do all stories function in an eerily similar way? John Yorke, creator of the BBC Writers' Academy, has brought a vast array of drama to British screens. Here he takes us on a journey to the heart of storytelling, revealing that there truly is a unifying shape to narrative forms - one that echoes the fairytale journey into the woods and, like any great art, comes from deep within. From ancient myths to big-budget blockbusters, he gets to the root of the stories that are all around us, every day.

John Yorke is Managing Director of Company Pictures, the UK drama independent producing Skins, Shameless, The White Queen and Wolf Hall. For many years he's been responsible for a vast array of British drama, as both Head of Channel Four Drama and Controller of BBC Drama Production. In 2005 he created the BBC Writers Academy, a year-long in-depth training scheme which has produced a generation of successful television writers. He's also worked as Editor of The Archers. John is Visiting Professor of English Language and Literature at the University of Newcastle-upon-Tyne.
