There has been a lot of internet game show conversation about the daytime schedule changes starting today, April 21st. An hour of classics leaves weekdays while Blockbusters and Press Your Luck appear early weekday mornings. The overall weekly airtime for classics shrinks from 21 hours per week to 17 hours per week, out of 138 programming hours (15.2% down to 12.3% of pre-1990's per week).
Meanwhile, Whammy! and Chuck Woolery's Lingo are relatively older shows, but just not ancient. We'll have to see how they'll do in the former pre-1990's slots.
Typically modern shows (post-2000) do poorly in the 11:30am (ET) timeslot. I remember around 2012 GSN tried a string of shows then, including Chain Reaction, Jeopardy! and Woolery Lingo at 11:30am and none really stuck.
One part of the schedule I do not agree with now is the 11:30am to 1pm (ET) weekday lineup with Chuck's Lingo, Inaba 1 vs. 100 and Engvall Lingo. Two shows within recent history that appeared to work there have been Karn Feud and Shop 'Til You Drop, which both had double runs in the noon hour in the past year. If I were GSN, for a better transition from pre-2005 shows in the morning to O'Hurley Feud and Catch 21, I would have aired Karn Feud/Shop from 11:30am to 1pm, in one order or another.
I do think Whammy! will improve ratings in the morning and build a better lead-in to The $25,000 Pyramid. It's from 2002, anyway, so it's pretty old to everything else GSN shows after 6pm (ET) on their schedule. Plus, it's not a bad show and not really rerun as much as it could be.
Plus, it's a smart move to air Chain Reaction again. The Pyramid (GSN) at 2:30pm (ET) was a good performer but seemed drop-off from Catch 21. If I were GSN someday soon, I'd double up on Catch 21 in the 2pm (ET) hour and add an hour of Chain Reaction to replace either Deal or No Deal, Shop 'Til You Drop or 1 vs. 100 (NBC), because at least one of those hours needs to go.
