I Found Out KSLA (Channel 12 - CBS) in Shreveport, LA picked up Monty Hall's Split Second right before 2 Syndicated Talk Shows from Multimedia Television (Sally Jesse Raphael & Donahue)
KSLA was owned by Viacom, which syndicated Split Second in the US and IIRC, all five of the stations they owned had it some capacity. I can vouch for two others.
WVIT 30 (NBC) New Britain-Hartford, CT: 12:30 PM (punting
Wordplay to WHCT 18)
WNYT 13 (NBC) Albany, NY: 12:00 PM (
Super Password was already airing on WUSV 45 until that station shut down in early 1987)
Regarding WNYT, they would continue using
Split Second as random schedule filler well beyond 1987, to the point of
airing it at 7:30 PM for a week in September 1989 as filler between losing Win Lose or Draw and Hard Copy premiering.
Schedule data for the two other Viacom-owned stations of this period - KMOV 4 (CBS) St. Louis and WHEC 10 (CBS) Rochester, NY - seems to be unavailable online.
