Nope - there were reruns then. A show's year typically went something like:
Fall season (13 new eps)
Spring season (13 new eps)
Summer (more reruns)
Shows no longer in production might be shown as reruns in a regular afternoon or weekend slot - I remember watching The Twilight Zone
, Outer Limits
, One Step Beyond
, The Rifleman
, The Real McCoys
and other shows in those timeslots. Summer would be mostly reruns until the early 1970s when the idea began to catch on of introducing a new show as a summer replacement series.
