Quoting Art Fleming from an interview he did in "The TV Collector" from
Feb. 1983 on the original Jeopardy:
WHAT ABOUT PRINTS OF THE SHOW ON FILM OR TAPE?
"I have none at all. I wish I did. They were all destroyed, and Merv Griffin's company has I believe, only 3 episodes of different periods of our development.
Jeopardy was one of the few shows that could not be repeated because we had
a recurring champion that was permitted to play for 5 times. In syndication,
the tapes are, what was called 'bicycling'. In other words, in NY, you might
see episodes 1,2 and 3. In Cleveland at the same time, 4, 5, and 6 would be
shown, and in San Francisco, 7, 8, and 9. So this would screw up the
sequence and that's why it was decided never to go into syndication with the
tapes we had."
Sounds a bit confusing, and he may have been referring also to the
syndicated version of J! from 1974-75....
