San Diego daytime network TV had numerous daytime pre-emptions and tape delays that it's almost impossible for me to keep track of it all.
Note that this is Pacific time.
When KGTV was KOGO and an NBC affilliate, it aired all of NBC's daytime block except the noon-12:30 block (Three on a Match, Let's Make a Deal, etc.) When Days expanded to an hour and NBC's west coast feed for PM shows shifted back 1/2 hour, the 3pm slot (Somerset, which aired at 2:30 PT) was pre-empted by KGTV and was eventually cancelled.
When NBC moved to KCST (now KNSD) in 1977, from memory, it aired Phil Donahue from 9am-10am, pre-empting the first hour of NBC's shows. It ran NBC's shows from 10am-noon, then the local news, then the PM shows 12:30-3pm. It aired Hollywood Squares (a 9:30 show) at 4, then the Gong Show (a 3pm show) at 4:30. As NBC's schedule changed, and Sally Jesse Raphael was added to the 10am-10:30 slot, KCST aired the network Wheel of Fortune at 3pm sometime in 1983-85 or so. I'm not sure when they canceled their local noontime news, which shifted to 11:30 in 1979, then 11am later on.
KFMB channel 8 was notoriously preemptive on the 3-3:30pm slot, with two exceptions. In 1976, it carried Tattletales instead of airing syndicated shows or movies. In 1979, it aired the M*A*S*H reruns (that aired at 3pm on CBS) at 4:30, and here's the funny part, when M*A*S*H went into syndication that fall, KFMB bought the rights and kept it at 4:30, thus no longer airing the 3pm CBS half-hour slot.
ABC on XETV's days: pre-empted All My Children during the entire time (began airing on KCST in c. 1971), and never aired One Life to Live at 3:30 in favor of cartoons. It aired Dark Shadows at 4pm, but once that got cancelled, it began airing General Hospital, another soap it preempted, at 3pm.
In 1973, KCST got the ABC affilliation and aired the entire ABC daytime block in pattern from 11:30-4:30, then in 1974 from 10:30-3:30 when the ABC west coast feed went to an altered pattern that's way too complicated to explain for now. KCST added a noontime newscast in c. 1975 at 11:30, then shifted it to noon later. It preempted some ABC shows. Not sure which ones.
In April of 1977, All My Children expanded to an hour from 12pm-1pm, but KCST aired it on a one-day delay from 12:30-1:30, and bumped Ryan's Hope. In July of that year, KGTV got the ABC affilliation and kept the daytime ABC pattern KCST had except for Edge of Night (a 3pm show) as KGTV aired the news at noon also. Ryan's Hope never aired on KGTV. When One Life to Live and General Hospital took the 1-3pm block, KGTV aired All My Children (still on a one-day delay) from 11am-NOON, then news, then Family Feud (a 11am show) at 12:30. In 1979, KGTV shifted the news to 11:30 and aired the ABC shows (except RH and EON) in pattern.
In the 80s when ABC's early daytime shows were tanking, KGTV did a lot of premptions, sometimes airing "Lifestyles of the Rich and Famous" at 11am instead of 10am for example. There were so many that I can't keep track of what didn't air, but the Match Game revival of 1990-91 at 11am didn't air on KGTV for sure.
KGTV delayed Port Charles (a 11:30am show) to 1:10am for most of its run. I can't recall if they aired The View briefly at 1:10am before shifting it to 10am shortly afterward.
I remember this in the fall of 1986. KFMB shifted the CBS two-hour morning news block from 6-8am to 7-9am, and its local Sunup show from 8-9 (where it preempted Captain Kangaroo for most of its run, it ran briefly on XETV from 1974-78?), to 9-10am, bumping off the first hour of CBS daytime shows, which shifted over to, oddly, KGTV. It was weird that an ABC affilliate was airing an hour of CBS shows. KGTV ran Eight is Enough reruns from 10am-11am, then Robin Leach's show at 11am, then news at 11:30 in 1986-87.
I believe KCST didn't air the first hour of David Letterman's 90 minute show when it aired from 9-10:30am in 1980. I don't think KCST aired The Doctors when it aired at 11am during its waning days and aired the news instead.
I'm not sure what the local affilliates had against airing some game shows in favor of movies and talk shows. Had to watch them on the L.A. stations. Some were good, but others were better off pre-empted. You be the judge.
There's more. For a while in 1974-75, KFMB preempted Match Game '7x at 2:30-3 so it could air movies, but XETV picked up Match Game for a while. In 1978, XETV briefly aired Edge of Night and Ryan's Hope from 11am-NOON, opposite KGTV's All My Children. Not sure why but that experiment flopped.
