Guiding Light
"The Guiding Light" was broadcast first by CBS Television on June 30, 1952, replacing the canceled soap opera "The First Hundred Years". These episodes were also 15 minutes long. During the period from 1952 to 1956, "The Guiding Light" existed as both a radio and television serial, with actors recording their performances twice for each day that the shows were broadcast. The radio broadcast of "The Guiding Light" ceased production during 1956, ending this overlap.
