The programme featured Professor Cyril E. M. Joad, previously rejected for radio for his strange speaking voice; the writer and zoologist Julian Huxley; and the loud and entertaining Archibald Bruce Campbell. The programme first aired under the title "Any Questions?" and drew a small audience and few questions. However, within a few weeks it had caught the zeitgeist of the nation, gaining an audience of 11½million. The series was extended from a run of 12 episodes into an open-ended series that ran into the 1950s.
