Here is my info on pre-emptions thru the years:
In Michigan , our CBS station WKZO-TV (now WWMT) Kalamazoo carried every CBS game show, including the original Password (they also aired the color reruns from 1967-70,before ABC revived Password), TJW, TPIR and MG. The Lansing CBS station, WJIM-TV (now WLNS) usually bumped Tattletales ,both versions except for a time when it aired at 11am in 1975 and later the last 1 1/2 years of MG'77/'78/'79 were not aired and Body Language wasn't aired on WLNS and neither was the last PYL's in 1986.
WOOD -TV 8 NBC Grand Rapids did not air the 12:30 or 1:30 NBC shows due to local news and Merv Griffin before he moved to CBS to face Carson, or the original MG. In the 1970's and 1980's they bumped various shows including The Gong Show,(although WOOD did air the night version), MGHS and SP.
WILX-TV Lansing bumped the NBC AM game shows from 1959-70. I know Matt Ottinger remembers that like I do, because of WILX's shared time arrangement with WKAR-TV (then WMSB)Michigan State University's NET/PBS station on Channel 10 from 3/1959-9/1972. So they signed on at 7am with The Today Show and then at 9am WMSB came on with local and NET/PBS shows like Mr. Rogers and Sesame Street then back to WILX for NBC's soaps and also for You Don't Say and the original MG and various syndie shows and later the local and NBC news and then back to WMSB and tehn back to WILX for NBC shows like Laugh-In or Jeannie and then sign off after Johnny Carson. There were no games on 10 from NBC from 9/1969 when YDS and the original MG were canned until the summer of 1970 when the original Concentration, Hollywood Squares and Jeopardy! were on a tape delay from 3-4:30 when Mike Douglas came on,but the original $OTC with Jack Kelly and later Joe Garagiola was not seen in Lansing until 9/1972,and The Who, What or Where Game with Art James was also not seen on WILX until 9/1972. The shared-time deal ended on 9/10/1972 when WILX went Full-Time NBC and WKAR-TV came back on 23. WILX carried all of NBC's games until 1979 when the new version of J! with Art Fleming moved in at noon, but Action News aired at the time, and the last year of Perry CS was not aired and neither was the last five months of P+(I would see them later on GSN). And I never got to see Just Men ! on WILX or WOOD due to news. Can someone tell me if that show still exists? I'd love to see GSn air it.
WJRT-TV Flint carried virtually all of ABC's shows, WZZM -TV Grand Rapids tape delayed Password and later Family Feud due to Eyewitness news, and WUHQ-TV (now WOTV) Battle Creek aired all of ABC's games as scheduled.
Then in 1983, I moved to Sacramento and here's the scoop on lineups here:
When I got here KCRA 3 aired WOF at 10 am, then TTD, and then The New Battlestars, which left the air a few weeks after I moved, and Dream House on a tape delay took over, but GO! came in October, bumping DH, and $OTC was on a tape delay due to a local talk show called Look Who's Talking . We also never got to see Your Number's UP or Time Machine. KCRA did air Hot Potato and SP and also aired Fantasy and later MGHS on a one-week tape delay. We did not see the last episodes of MGHS in the summer of 1984 because KCRA wanted to do an afternoon version of Look Who's Talking,but it flopped.
Later , KCRA bumped CC but got it in 9/1989, and also bumped the last 1 1/2 years of $OTC and also Wordplay (Wordplay and CC were on what's now My58 in 1987,), and also TTTT90.
KXTV 10 carried all of the CBS games but in the early 1990's bumped TPIR, but public outcry reinstated TPIR. Now KXTV is ABC and when the Kings are on they often send J! to 1am and no WOF. At least I get WSBK Boston on Dish Network so I won't have to worry about pre-emptions.
KOVR 13 had many of the ABC games, but did not air MG90-91. I watched MG 90-91 on KGO in San Francisco on cable. KOVR is now CBS.
KDWB 20 in San Francisco (then KOFY TV 20) had many of the CBS and NBC games bumped by KPIX CBS 5 and KRON 4 , when they were with NBC in the 1970's and 1980's including, TPIR, PYL, CS-Eubanks, CC, BL, Fantasy,$25K Pyramid among others. Later KPIX began airing TPIR and KRON (which lost NBC to KNTV 11 and is now My TV 4 in the Bay Area) began airing CC.
