"General Hospital" is the longest-running American soap opera still in production and is the lone remaining daytime soap on the ABC network as of 2015. The highest-rated soap opera during its heyday in the late 1970s and early 1980s, the show celebrated its 50th anniversary on April 1, 2013.
During the golden age of soap operas, ABC featured several hit daytime dramas, including Agnes Nixon's "All My Children" and "One Life to Live." Although both shows had been on the air for over 40 years, they fell victim to the steep decline in daytime soap opera viewership and were cancelled on April 14, 2011.
The most unusual daytime soap opera was ABC's "Dark Shadows," a gothic horror program that ran from 1966 to 1971. The show featured the vampire Barnabas Collins and developed a cult following among teenagers who could return home from school and still catch the late-afternoon program. The show spawned a later nighttime version and several movies.
