In case you haven't noticed, they're really trying as hard as they can to get people to sign up for Peacock. If that means alienating you from the broadcast coverage, then they're fine with that. For NBC, the future is Peacock. For CBS, the future is Paramount.
But it depends. The night of the skating, when Nathan Chen won the Gold, they ran the entire competition without much interruption, and later said it had been sponsored by Toyota. So if they have something particularly hot that they expect people to watch, they find ways to lessen the spotload. But on a Saturday night, when viewing is low anyway, it probably doesn't matter.
Whatever they are doing with the broadcast coverage, prospective Peacock customers will transfer the broadcast presentation style to the streaming platform. Why pay for such bad commentary and the horrible U.S.A. team focus censorship (editing)?
It's actually about NBC's presentation--first impressions are everything! NBC hypes the games so much that the biographies, promotions, etc. are overdramatized. Wish the games were back on CBS again!
