The early years of "The Guiding Light" concentrated on Reverend Dr. John Ruthledge as he lent support to his flock and offered counsel to the townspeople, like the often troubled Holden family. The series examined moral dilemmas and social issues in a fast paced way and wasn't shy about integrating commercials into the flow. As the years went on, some other families came to town, notably the Bauers, who managed to channel much of Phillip's own experiences as the child of an immigrant family into the show. The show didn't take place in Springfield, but in Five Points before moving to Selby Flats in California. It featured shocking stories of children born out of wedlock, the return of long absent relatives, secret affairs and pseudo-incestuous relationships.
Here is a complete episode of the radio series from June of 1941.
