From its inception in 1922 the BBC pioneered a new medium in the education of children. This article traces the origins and development of a particular broadcast, "Children's Hour Prayers," a short worship time for children (appended to "Children's Hour") which began in wartime, and ended, along with the host programme itself, in the early 1960s. This article considers the ways in which adult-child relatedness is challenged and changed by the broadcasts, and how disputes over the best approach to teaching the young to pray affirmed the importance of treating children maturely, valuing their religious experience and communicating with them authentically. This paper concludes by arguing that the programme makers' straightforward approach in exploring religious ideas with children was a forerunner of pedagogical development in school RE, speculating whether the demise of "Children's Hour Prayers" is indicative of the incipient de-Christianisation of Britain from the 1960s onwards.
