Another two that cross my mind occasionally. I might be getting a little creative here.
Ever since the late-70s, Merv wanted a syndicated version of
Wheel. IIRC, he almost got 20th Century Fox to distribute the show in 1980, and I'm guessing it would've been a 20CF companion to
Dance Fever. That being said, I don't think it becomes the massive hit it became in '83 and I predict it gets the axe around the same time as
Dance Fever.
In this alternate universe I see it getting a short-lived reboot in the mid-90s, then another one in the late-90s/early-2000s that runs to this day. Since evening
Wheel doesn't give
Feud a run for the money, Dawson goes a couple more years on syndicated
Feud and passes off the torch to Ray Combs in '88. The ABC version still goes off the air in '85. Oh, and since
Wheel went off the air around '87 Pat Sajak gets a CBS gig, but in 1993. Letterman replaces Carson in '92 and Jay Leno gets something in syndication.
The other one is Dean Goss's
LMAD continuing into '86, and doing just well enough to make it to '87-'88 before finally getting canceled.
