《指路明灯》的前身是广播肥皂剧,1937年在美国全国广播公司中以15分钟一集的长度连续播放,1952年改为电视版在哥伦比亚广播公司播出。Guiding Light takes place in the fictional Midwestern town of Springfield. In its early years the stories centered on the middle class Bauer family, but later the wealthy Spauldings, Chamberlains, and Lewises, along with the working class Reardons and others, took their own places of prominence, though the Bauers remained the heart of the show.
