ABC promoted the first ever (English-language network) Puerto Rico countdown on New Year's Rockin' Eve tonight (shhhh...Univision, Telemundo, and WAPA airing that for years doesn't count somehow)...
Completely forgetting that most of their affiliates don't usually like to start their news at 11:01/10:01 for no good reason, especially on a night where five minutes (and three minutes of ads) are already taken away for New York coverage. Both my ABC affiliates (WBAY and WISN) have hard master control clocks and went right to their news at 10 on the dot, and I'm sure a good percentage of ABC affiliates in the Central/Eastern Time Zones did too. Very bad planning on ABC and Media Rights Capital's part.
Making it worse? They didn't even count down for a full minute, it was on a broadcast delay, and when they did start the countdown, it was the top of the hour and there was no natural lead-in outside chaos on stage desperately getting the crowed to get hyped for the countdown, thus the affiliates made the right choice in going to news.
I'm not even going to get deep into the unmasked disaster that is CBS in Nashville tonight (say everyone is triple-vaxxed all you want, people will fake their cards and there's no breathing room in those crowd shots); at least the NBC coverage does have a mostly-masked crowd and compelling performances from Miley (Pete Davidson though...noooooo), and outside that bad clocking, ABC is fine, though the late-late night recorded performances from LA and previous years have been used as a primetime Plan B.
ETA - ABC also forgot that the Friday night Mega Millions drawing is a thing stations air (which originates at WSB and is always aired there and all Cox stations), so the San Juan countdown was also pre-empted for that.
