Some thoughts to ponder about the numerous markets the "Mother of All TV Listings" covered:
1) The year-long CST for all of Kentucky made things a bit odd for station scheduling. Some examples:
WAVE, Louisville--its Morning Show was probably during normal circumstances a full hour in length, at 9 a.m. ET, before the 10 a.m. NBC feed; The Mike Douglas Show may well have aired at another time normally and was dispatched to 2:30 to fill in the gap between Another World and the afternoon movie;
WHAS, Louisville--the midday Omelet displaced, out of necessity, several daytime shows, which were tape-delayed for later in the afternoon (most notably As the World Turns, at 3 p.m.);
all Kentucky stations--the local newscast moving to after, rather than before, the network newscasts, meaning that Prime Time Access was shortened by a half-hour, probably entailing the relocation of some of those programs to 5 p.m.
Can you not imagine all the confusion that this initially created, and all the in-house promotion, both on-screen and off, that stations had to do? I am sure station managers did not have a very high opinion of Kentucky state government as a result ("Damn those stubborn lawmakers! Why can't we do like the rest of the country and put up with it?") By 1976, the Feds ditched the concept of year-long Daylight Saving Time, so that controversy died down.
2) 1974 was one of the last years that stations, by and large, carried most if not all their networks' feeds on schedule. In the past, pre-emptions were primarily a primetime phenomenon, something that third-rated stations normally did to boost their local ad spot revenues. But in the early 1970s, the networks were at the height of their power over affils.
Notice that the only market which shuffled around or rejected programs on a large scale was Cincinnati. That market's stations, except for indie WXIX, were all the flagship outlets for their respective owners (WLWT, Avco; WCPO, Scripps-Howard; WKRC, Taft). It does not take much imagination to figure that corporate brass, due to close proximity, bore harder on their flagships' managers to get top local spot rates. Tradition played a factor especially with WLWT, due to its long-running Paul Dixon and 50-50 Club, both highly established daytime fixtures for viewers in the Ohio Valley. A very unusual side-effect was ABC affil WKRC picking up several pre-empted NBC daytime shows, including Somerset, a soap packaged by none other than Cincinnati's Procter and Gamble! Stranger still, there was an indie in the market, and it opted for cartoons and sitcom reruns!
All in all, the other markets stayed in line with network intentions. This era would not last long, though, particularly in daytime, in part due to a show that originated from the Avco "WLW" regional network: Phil Donahue.
3) One extreme oddity: small Paducah, Kentucky, population probably no more than 25,000 in 1974, had an independent station, while Nashville, population around 15-20 times that, did not (Louisville, about the same size of a market as Nashville, did with WDRB). The city of Nashville likely had more residents than the entire Paducah-Cape Girardeau-southern Illinois market did, or close to it. But Nashville's channel 17 had sat idle since 1971, when WMCV-TV went bust after three years of struggle to get a ratings foothold. The license changed hands repeatedly until 1976, when Reel Broadcasting re-launched the station as the current-day WZTV. American broadcasting has not always had the cookie-cutter sameness in every part of the country, as it has since the 1980s. There were haves and have nots.
And WDXR was surely a have not, as it did not sign on until 2:30 p.m. and could only manage one local program, a kiddie show. With three network affils that were not exactly state-of-the-art technically or otherwise, how could one expect a UHF indie to possibly be better? Not surprisingly, by 1975 or so, the owners apparently ran out of money (or patience), and with no one else interested in restarting channel 29 (remember, no FOX or minor networks back then) and thus no buyers, the license wound up in the hands of Kentucky Educational Television, who obviously got the license converted to non-commercial in order to supplement its Murray, Ky. translator for the "Purchase" region between the Ohio and Mississippi rivers.
The mere fact that only three of the 33 listed stations were unaffiliated tells us that television was a far different animal than today.
