During this period, the show was broadcast on Chicago's WGN (AM), one of the founding members of the Mutual Broadcasting System.

In 1936, Dick Huddleston of Waters petitioned the United States Post Office to change the town's name to Pine Ridge.

Over the course of its life, Lum and Abner appeared on all four major radio networks: NBC, Mutual, CBS and ABC (formerly NBC Blue).
