In Our Time has been the cornerstone of broadcasting every Thursday morning on BBC Radio 4 for the past twenty years, with over 800 episodes since its launch in October 1998. Presented by one of Britain's greatest champions of the arts, Melvyn Bragg, the show explores ideas across history, religion, philosophy, science and culture. With a vast array of contributors from the world of academia, such as Mary Beard, Angie Hobbs and Diarmaid MacCulloch, it is one of Radio 4's most successful programmes, attracting a weekly live audience exceeding 2 million listeners, and, per episode, it is one of the world's most downloaded podcasts.

To honour this major anniversary of BBC broadcasting, this beautifully illustrated book provides a lively and colourful guide to fifty of the most captivating discussions from the past two decades of In Our Time, as chosen by Melvyn and the producer Simon Tillotson, and, influenced by listeners who have recommended their favourite programmes from those years.
