In the 1940s the game became a popular radio panel quiz show, Twenty Questions, first broadcast at 8pm, Saturday, February 2, 1946, on the Mutual Broadcasting System from New York's Longacre Theatre on West 48th Street. Radio listeners sent in subjects for the panelists to guess in 20 questions; Winston Churchill's cigar was the subject most frequently submitted. On the early shows, listeners who stumped the panel won a lifetime subscription to Pageant.
