What is (or was) the longest running soap opera?

The American soap opera The Guiding Light started as a radio drama in January 1937 and subsequently transferred to television. With the exception of several years in the late 1940s when Irna Phillips was in dispute with Procter %26amp; Gamble, The Guiding Light has been heard or seen nearly every weekday since it started, making it the longest story ever told. Other American soap operas that have been telecast for more than thirty years (and are still in rotation) include As the World Turns, General Hospital, Days of our Lives, One Life to Live, All My Children, and The Young and the Restless.
