The popularity of the service was established when the service began to be broadcast by the British Broadcasting Corporation in 1928, and, except for 1930, has been broadcast every year since. During the 1930s the service reached a worldwide audience when the BBC began broadcasting the service on its Overseas Service. Even throughout the Second World War, despite the stained glass having been removed from the Chapel and the lack of heating, the broadcasts continued. For security reasons, the name "King's" was not mentioned during wartime broadcasts.
