What was (were) the first network series to have its reruns subsequently packaged and syndicated? The practice is so ubiquitous and longstanding that tend to we forget that it had to start sometime. I'm guessing, off the top of my head, that this was not done, or not done much, until the late 50's/early 60's? Also, in addition to the "first," was there a point at which the practice started to become more commonplace? I imagine it wasn't too profitable until there were more independent stations on the air with a lot of hours to fill.
