(written from a Production point of view)
The Star Trek Viewers Choice Marathon aired 28 September 1991 immediately before the Star Trek 25th Anniversary Special. Like the special, it was hosted by William Shatner and Leonard Nimoy. There were ten episodes chosen for the marathon, which were shown in order from #10 through #1. There was also a shortened version of the marathon shown in some markets of the final three episodes, which were the top ranked episodes.
In the order they appeared in the marathon, ranked in reverse order (the top ranked aired last).
