The ceremony was shown with a delay in the USA apparently, and according to an article:
NBC responded to online criticism by saying that its team needed time to edit the ceremony and put it into context for viewers in the US.

"It's a cultural ceremony that requires deep levels of understanding, with numerous camera angles and our commentary laid over it.
"We think it's important to give it the proper context. And primetime is still when the most people are available to watch."
