The final episode of The Guiding Light (its 15,761st) airs today on CBS. I wrote about the network’s announcement that the soap would be ending back in April. A special finale section at the CBS website for The Guiding Light can be found here. CNN.com has an article about the end of the soap as well as the demise of the soap operas in general.
The soap premiered on June 30th, 1952. You can watch the March 4th, 1953 episode for free courtesy of the Internet Archive:
