This is unscientific, so I am going by shows over the years where I can recall every rerun.
Star Trek TOS and TNG.
M.A.S.H.
The X Files
Law And Order
Twilight Zone
All In The Family
I am pretty confident on these, off the top of my head.
However, I probably have more from the 70’s, but since I can barely remember that decade, I will not try to remember any more. (too much fun)
Highlander
Star Trek
Star Trek: The Next Generation
Star Trek: Deep Space Nine
Kindred: the Embraced (see if anyone remembers THAT one)

Gilligan’s Island
Brady Bunch

Partridge Family
Barney Miller

Gee, I wanted to say something funny – like naming a show that got canceled after only one episode – but I couldn’t think of any off the top of my head. Anyway…
STAR TREK (the original)
THE OUTER LIMITS (the original)
TWILIGHT ZONE (the original)
I would like to add TWIN PEAKS, but I missed one episode, the second from the last. (Actually, come to think of it, there’s one rarely-aired episode of TZ episode with George TakaiI can’t recall having seen all the way through.) And I hope to catch up with the episodes of SOUTH PARK I missed.
There’s only one I can think of off the top of my head, and that’s Scarecrow and Mrs. King. But I think I may have also seen all the eps of The Pretender. But don’t quote me on that.
Are you sure of that one? The episodes from season 4 are all an hour long, and I have never seen them in reruns. (But then I haven’t had cable for years). See a season 4 episode guide
Babylon 5. All episodes three times. And to prove it I have the videotapes. One set to keep, one to lend out, and one set to give to my nephews when they get old enough.
Star Trek-TOS
MASH
Probably a couple of others but I didn’t keep track.
At one time I, too, was a tv-aholic. Thank God for the internet. I merely switched addictions.
I Love Lucy
The Lucy Show
(Can you tell I like Lucille Ball?)
Gilligan’s Island
F Troop
The original Dark Shadows
The Andy Griffith Show (both black & white and color episodes)
The original Star Trek
Perry Mason
The Brady Bunch
Bewitched
I’m pretty sure there are a few more, but I can’t think of them right now. I’m only on my 1st cup of coffee. When the brain kicks in, I’ll try to get back with ya.
