Why does radio still matter in 2017? We ask the controller of BBC World Service English, radio presenteter Robin Ince and the creator of an innovative Indian radio station, plus veteran journalist Graham Holliday on radio in Rwanda today, technology writer Mark Frary on why it's so easy to create your own radio station cheaply, plus the 98-year-old granny who is a US radio celebrity. Plus articles by Madeline Thein, and Laura Silvia Battaglia reports from Mosul on the people who continue to run Alghad FM despite the bombardment.
