IT used to be on ABC that at midnight eastern that New York and Las Vegas would celebrate the new year on New York time. I would wonder why Las Vegas would celebrate at 9 PM. They finally came to their senses and realizes that the whole nation isn't in the eastern time zone.
What's weird is that they added AST before MST and PST. Sadly, the Puerto Rico countdown seemed to be shoehorned in without the fanfare that the countdowns at New York and New Orleans have. Apparently it wasn't just numbers on a concert screen, but they didn't bother to show the star until after 11:30!
They had heavily promoted the AST countdown for Puerto Rico too...but at least in my area, in the eastern time zone, they had a commercial break at 10:58 and cut away to the news at 11, so it was never aired.
The NO countdown was also delayed on ABC by 30 seconds, so it was 12:00:30 in the CTZ at the time the countdown ended.
Saw this as well. The clock on the screen hit 10:59 CT, the host Billy Porter is sloppily handing out beads, and the countdown started from 60 a half-minute late.
Overall, the whole event was a bit more sloppily put together than it was in previous years. Covid no-doubt made it a bit harder to do what they normally would do, but it certainly didn't seem very smooth at times.
At the very end of the broadcast, which I was still awake for around 2:10am, they thanked the producer and did hint about several last-minute changes that probably did make for some issues they had to overcome on the fly.
