Growing up in Portland, Oregon, the CBS station will the king of uncleared shows until now. In the 1970s and early 1980s, KOIN-TV didn't air "The Price is Right." They aired "Donahue" at 9am and then a local show at 10am. When the local show was dropped in the early 1980s, KOIN aired reruns of "The Jeffersons" and "One Day at the Time" (CBS daytime) over "TPIR." I think KOIN either brought back or started airing "TRIP" around 1982. I don't know if KOIN first aired "TRIP" when it returned to TV in 1972 and then dropped it shortly after, but I was born in 1979.
Then, KOIN didn't aired "Search for Tomorrow" in the '70s as well. Portland one-powerful independent station KPTV (now a FOX station) cleared the show. KOIN did air the show in their last few years on CBS until moving to NBC in 1982.
When "Search for Tomorrow" moved to NBC, KOIN didn't not clear CBS' new soap opera "Capitol" in 1982. This was probably a good move for KOIN because they expanded their Noon newscast to an hour. It was only Noon newscast a few years later in the Portland market. Plus, it was a highly rated newscast. However, it would take many years for KOIN to clear "Bold and the Beautiful." KOIN did air "Bold" briefly in the Fall of 1989, but it aired at 3pm. When Emmis brought KOIN-TV from Lee Enterprises in 2000, "Bold and the Beautiful" was finally aired in Portland. I am not a big soap opera guy, but that was the only uncleared show that bothered me because it that time "Bold" was the second-highest rated soap opera in the country. Now, KOIN airs all of the CBS shows, but airs "Let's Make a Deal" at 9am.
As for KATU, the ABC station in Portland, they have been the most loyal to the ABC network. I can't speak before 1979, but they have aired majority of their daytime shows. They even aired the final seasons of "The Edge of Night" when many ABC stations dropped it completely in the 1980s. However, they aired "All My Children" at 3pm for many years until recently. KATU aired News or syndicated programming at Noon in the 1980s.
As for KGW, the NBC station, it was a mixed bag. They did air most the the NBC daytime shows, expect for "The Doctors" and "Texas" in the early 1980s. I don't remember those show anyway. KGW did air movies at 2pm in 1980. I think "Texas" did air on KGW in 1981 when they dropped daytime movies completely from their schedule. Then, KGW didn't air the first hour of NBC daytime programming in the Fall of 1982 because of local/regional programming. Plus, KGW aired syndicated programming at 11:30am in the early 1980s. I do remember KGW airing syndicated shows like "Newlywed Game," "Tic Tac Dough" and "Anything for Money" at 11:30am, but I don't recall dropping NBC programming during the mid 1980s. They did air "Super Password," "Wheel of Fortune," and "Sale of the Century."
In 1987, KGW did not air the NBC version of "Win, Lose or Draw" because the daytime version aired on KATU at 7pm. KGW aired their own local game show called "On the Spot."
