In 1943, after 4,091 episodes, the radio program went from a 15-minute CBS weekday dramatic serial to an NBC half-hour weekly comedy. While the five-a-week show often had a quiet, easygoing feeling, the new version was a full-fledged sitcom in the Hollywood sense, with a regular studio audience (for the first time in the show's history) and an orchestra. More outside actors, including many black comedy professionals, such as Eddie Green and James Baskett, were brought in to fill out the cast. Many of the half-hour programs were written by Joe Connelly and Bob Mosher, later the writing team behind "Leave It to Beaver" and "The Munsters". In the new version, Amos became a peripheral character to the more dominant Andy and Kingfish duo, although Amos was still featured in the traditional Christmas show. The Christmas show also became a part of the later television series. The later radio program and the TV version were advanced for the time, depicting blacks in a variety of roles, including successful business owners and managers, professionals, and public officials, in addition to the comic characters at the show's core. It anticipated and informed many later comedies featuring working-class characters (both black and white), including "The Honeymooners", "All in the Family," and "Sanford and Son."
