There is only one example I can remember of any inexplicable preemptions happening in the Albany NY, area. In early 1994 a new Peanuts special “You’re in the Super Bowl Charlie Brown” aired on NBC. This was the only Peanuts special to air on NBC instead of CBS (until the 00s when they switched over to ABC) because NBC aired the Super Bowl that year. I was a VERY hardcore Peanuts fan as a kid and new specials were like Christmas to me, especially by the early 90s when they were becoming rarer and rarer, it was actually the very last new special to air on network TV during Charles Schulz’s lifetime. So that night my family tuned into WNYT and were greeted with some kind of news documentary or something, I don’t know what it was it was a really long time ago, and as you can imagine I was very upset about it.
This preemption must have been decided at the last minute because the special was still listed in the TV booklet that came with our paper's Sunday Edition that week, that was how we knew about it in the first place, and I remember it was supposed to air on a Tuesday because we switched over to Full House when it failed to show. It's possible that we were looking at an outdated TV booklet or something, but that seems like a stretch. I know that nowadays most Peanuts fans usually consider this particular special to be amongst the worst ones, but that's besides the point, kid me still enjoyed it when, a couple of weeks later when we were visiting my aunt in Syracuse, my parents managed to get me the VHS at a Shell gas station, who were selling them as a promotional item since they sponsored the special.
This particular promotional VHS is the only time that the special has ever been made available after it aired because of the legal issues with things like the fact that the kids were all wearing uniforms with real-life team logos on them , and I don’t ever remember there being any Shell stations near where we lived and even if there were we had no idea they had them there, so it could be very lucky that we were visiting my aunt within the right time frame and that my parents decided to fill up at a Shell station.
Edit: Another story I just remembered. On the day that Dale Earnhardt died WXXA interrupted a new episode of Futurama to announce it. Don't mean to be disrespectful but I was very annoyed that they didn't wait until a commercial break to do that, especially because they re-aired the exact same announcement during a commercial break during that night's Simpsons episode instead of interrupting it
