Agnes Nixon initially produced her series "One Life to Live" and "All My Children" through her own production company, Creative Horizons, Inc., and kept a complete archive of monochrome kinescopes until ABC bought the shows from her in 1975. When the network decided to expand "All My Children" from 30 minutes to a full hour in the late 1970s, Nixon agreed on the condition that the network would begin saving the episodes. ABC complied, and full hour broadcasts began on April 25, 1977. However, different sources indicate that a warehouse fire destroyed the vast majority of the early-1970s kinescopes, or that erasures of the episodes continued. As a result, a few early episodes from these early years survive.
