The answer is Yes, of course.
As of yesterday (same day as its e-mail to
@Fireplace7890, USFS immediately started shouting from all its online rooftops about Peacock's upcoming coverage.
USFS published its full press release both on
usfigureskating.org and
usfigureskatingfanzone.com -- and added links to Peacock all over the place.
USFS social media platforms have been promoting the Peacock news, and I have no doubt that they will continue to do so.
Peacock also offers one-year options of $49.99 with ads and $99.99 without ads.
Good question, which interests me too.
AFAIK, the duration of archiving has not been specified.
I have seen only this brief reference to on-demand:
"Peacock Premium will feature select live event coverage as well as on-demand replay coverage of figure skating throughout the season."
