In July 1930, Gielgud was invited in his position as the senior drama producer at BBC radio to oversee the experimental transmission of a short play on the new medium of television. The play,
The Man With the Flower in His Mouth by Italian playwright
Luigi Pirandello, was chosen because of its confined setting, small cast of characters and short length of around half an hour. Transmitted live on the evening of 14 July, the primitive state of television technology at the time allowed for only tiny 30-line pictures with one actor visible at a time, but the experiment was nonetheless judged to have been a success, and was watched by the then Prime Minister,
Ramsay MacDonald. Gielgud remained in radio for the rest of the decade, also working occasionally in film, adapting his thriller
Death at Broadcasting House, in which he also appeared in a small acting role. In 1939 he returned to television for a time on a secondment to the
BBC Television Service at
Alexandra Palace, which was now a full-fledged, high-definition television network broadcasting to the London area. On secondment from his radio job, he produced one short play called
Ending It, an adaptation of one of his own short stories starring
John Robinson and
Joan Marion, transmitted on 25 August 1939. However, a full-length play he was due to direct, and which had even been rehearsed, was cancelled from its planned slot on the evening of 1 September due to the television service having been suspended earlier that day in anticipation of the declaration of war. Gielgud returned to radio for the duration of the Second World War, but shortly after the return of the television service in 1946, he moved across on a more permanent basis to become the Head of
BBC television drama. Although the BBC hoped he would have the same impact on shaping the genre in the new medium as he had done in radio, his time in charge was not regarded as a success, as many of the producers working under him felt he had no great liking for television or appreciation for what it could achieve that radio could not. In 1952, he left the television service, being replaced by the experienced producer
Michael Barry. In the 1950s, Gielgud was involved in directing a run of
Sherlock Holmes radio plays starring his brother John as the lead character, with
Ralph Richardson as
Dr Watson and Gielgud himself once appearing as
Mycroft Holmes. These were broadcast on the BBC's
Light Programme. By this time Gielgud was in conflict with junior colleagues in the drama department; unlike them he was unable to appreciate the work of playwrights such as
Harold Pinter and
Samuel Beckett. Beckett's
Waiting for Godot would have made its English début in a radio production had Gielgud not rejected it. ==Private life==
