I wouldn't doubt it. I can remember when WOAI (then KMOL),
Channel 4 in San Antonio, carried all of NBC's daytime programming
except 11:30 AM (CT), when it had its midday newscast (it didn't
dare go up against market leader KENS at noon), but it started
pre-empting 10:30-11:30 for Dinah Shore's syndicated show as well.
In WSB's last year or two with NBC, it also pre-empted 10-11:30 AM
for Dinah.
And who knows how many NBC affiliates in the Central time zone elected
to run Phil Donahue from 9-10?
While of course money is what it's all about, it was difficult in the pre-Bolen
era to find many NBC affiliates pre-empting Dinah's NBC show, "Concentration,"
"Sale Of The Century," "Hollywood Squares," and "Jeopardy!" (although I know of
several stations that delayed it to 1 PM). Because of "Jeopardy!" a number of
NBC stations (like Channel 2 in Orlando and Channel 4 in Greenville, SC) would
pre-empt "Who, What Or Where" in favor of local news at 12:30. "Three On A
Match" at 1:30 got good clearances--maybe not the full network (Channel 4
in Nashville had its "Noon Show" at that time)--but it was the only show NBC
aired at that time between the loss of "Let's Make A Deal" to ABC in 1968 and
the expansion of "Days Of Our Lives" to an hour in 1975 that lasted more than
a year.
Most of the games Bolen put on ("Wheel Of Fortune," "High Rollers," and maybe
"Celebrity Sweepstakes" might be exceptions) were inferior to the ones she canceled.
And the ratings showed it. Meanwhile, ABC, with "Happy Days," "Family Feud," "$20,000
Pyramid," and the soap block of "Ryan's Hope," "All My Children," "One Life To Live,"
and "General Hospital" ("Edge Of Night" had too many delays or pre-emptions), became
the network to watch in daytime.
