Second World War

Television broadcasting was suspended from 1 September 1939 to 7 June 1946, during the World War II, and it was left to BBC Radio broadcasters such as Reginald Foort to keep the nation's spirits up. The BBC moved most of its radio operations out of London, initially to Bristol, and then to Bedford. Concerts were broadcast from the Bedford Corn Exchange; the Trinity Chapel in St Paul's Church, Bedford was the studio for the daily service from 1941 to 1945, and, in the darkest days of the war in 1941, the Archbishops of Canterbury and York came to St Paul's to broadcast to the UK and the world on the National Day of Prayer. BBC employees during the war included George Orwell who spent two years with the broadcaster.

During his role as prime minister during the war, Winston Churchill delivered 33 major wartime speeches by radio, all of which were carried by the BBC within the UK. On 18 June 1940, French general Charles de Gaulle, in exile in London as the leader of the Free French, made a speech, broadcast by the BBC, urging the French people not to capitulate to the Nazis. In October 1940, Princesses Elizabeth and Margaret made their first radio broadcast for the BBC's Children's Hour, addressing other children who had been evacuated from cities.

In 1938, John Reith and the Government of the United Kingdom, specifically the Ministry of Information which had been set up for WWII, designed a censorship apparatus for the inevitability of war. Due to the BBC's advancements in shortwave radio technology, the corporation could broadcast across the world during the Second World War. Within Europe, the BBC European Service would gather intelligence and information regarding the current events of the war in English. Regional BBC workers, based on their regional geo-political climate, would then further censor the material their broadcasts would cover. Nothing was to be added outside the preordained news items. For example, the BBC Polish Service was heavily censored due to fears of jeopardising relations with the Soviet Union. Controversial topics, i.e. the contested Polish and Soviet border, the deportation of Polish citizens, the arrests of Polish Home Army members and the Katyn massacre, were not included in Polish broadcasts. American radio broadcasts were broadcast across Europe on BBC channels. This material also passed through the BBC's censorship office, which surveilled and edited American coverage of British affairs. By 1940, across all BBC broadcasts, music by composers from enemy nations was censored. In total, 99 German, 38 Austrian and 38 Italian composers were censored. The BBC argued that like the Italian or German languages, listeners would be irritated by the inclusion of enemy composers. Any potential broadcasters said to have pacifist, communist or fascist ideologies were not allowed on the BBC's airwaves. In 1937, a MI5 security officer was given a permanent office within the organisation. This officer would examine the files of potential political subversives and mark the files of those deemed a security risk to the organisation, blacklisting them. This was often done on spurious grounds; even so, the practice would continue and expand during the years of the Cold War.
