<human>: The mid-1940s was a lull in Groucho Marx's career. His radio show Blue Ribbon Town, sponsored by Pabst Blue Ribbon beer, had begun in March 1943 and had failed to catch on. Groucho left the program in June 1944, replaced by vocalist Kenny Baker until the show's end two months later. He also reluctantly appeared in two movies with brothers Chico and Harpo Marx, A Night in Casablanca and the lackluster Love Happy.  During a radio appearance with Bob Hope in March 1947, Marx ad-libbed most of his performance after being forced to stand by in a waiting room for 40 minutes before going live on the air. John Guedel, the Hope program's producer, formed an idea for a quiz show and approached Marx about the subject.  After initial reluctance by Marx, Guedel was able to convince him to host the program once Marx realized the quiz would be only a backdrop for his contestant interviews and the storm of ad-libbing that they would elicit. Guedel also convinced Marx to invest in 50% of the show, in part by saying that he was "untouchable" at ad-libbing, but not at following a script.  As Marx and the contestants were ad-libbing, he insisted that each show be filmed and edited before release to remove the risque or less interesting material. The show for the studio audience ran longer than the broadcast version. The president of Film Craft Productions, which did the filming, cited it as the first television show filmed before a live audience as part of a lengthy essay about production procedures.
