Not really.

I’m 34, and all of the shows from the 50s and early 60s were easily seen even in the mid 80s to early 90s. Everything from My Three Sons, Patty Duke, and the Honeymooners to Lost in Space and Star Trek.

Those were only shows that were 25-35 years old, like watching Threes Company and The Jeffersons today.

Those shows were easily seen in syndication on cable, in the 1980s and beyond. Not so much in the early 1970s.
