Living out west, there was a time in the early 1970s when ABC didn't schedule anything in the Pacific time zone before noon (except for repeats of The Brady Bunch at 11:30) - IIRC, it was Password at noon, Split Second at 12:30, Let's Make a Deal at 1:30, The Newlywed Game at 2:00, and The Dating Game at 2:30 - which made things easier for me to split my mornings between CBS and NBC. I think the only time I switched back and forth between the two was when both Baffle and $10,000 Pyramid were on at 9:30 AM.
