Radio Feltham was the first prison radio station in Europe, operating in HM Prison Feltham, a male juvenile prison and Young Offenders Institution in west London that housed up to 800 boys between the ages of 15 and 21. It launched in 1994 thanks to the work of advertising executive Mark Robinson, who developed the idea of a radio station to support young prisoners when they were at their most vulnerable, alone in their prison cells at night.
