At the BBC, Snowman was responsible for a wide variety of radio programmes on cultural and historical subjects, working with such established broadcasters as Bernard Crick, Robin Day, Bill Grundy, Lord Hailsham, William Hardcastle and John Vaizey while also helping develop the broadcasting careers of such younger figures as Susan Hill, Aled Jones, Norman Lebrecht, Roy Porter, Edward Seckerson and Lucie Skeaping. Snowman tended to specialize in ambitious series such as The Long March of Everyman, Whatever Happened to Equality?, A World In Common (world development issues), World Powers in the Twentieth Century, Northern Lights (a Radio 4 festival about the Arctic) and Fins de Siècle, an attempt to enter and recreate the sound world of the final years of each of the past six centuries. Many of these later appeared as books which Snowman helped edit. After leaving the BBC at the end of 1995, Snowman turned increasingly to writing and lecturing. From 2004 he has held a Senior Research Fellowship at London University's Institute of Historical Research; in 2010 he delivered the IHR Annual Fellows’ Lecture.
