On 30th September 2017 we mark the 50th anniversary of the transformation of the BBC’s Light Programme into Radios 1 and 2; and of the Home Service into Radio 4. (The transition from the Third Programme to Radio 3 took a little longer).
The Light Programme and Home Service were both, in their different ways, creatures of wartime. The Home Service was created on the outbreak of War in September 1939, as a merger of the former ‘National’ and ‘Regional’ programmes: it was feared that enemy bombers might use differential signals from regional transmitters as navigation guides. The Light Programme on the other hand was launched as the War ended, in July 1945, making use of the old ‘National’ longwave frequency which was now freed up again. When they were laid to rest in 1967, the Home Service was therefore only 28 years old, and the Light Programme a mere 22. Their middle-aged successors, Radios 1, 2 and 4, have lasted much longer.
