A couple of thoughts on the NBC announcement.
1. Nothing said about the Olympic Channel, and how it might be used. In 2018, they used it for a constant highlight show, IIRC, a reporters' roundtable, and victory ceremonies. But then, I realize yesterday's announcement was to focus on streaming, not broadcast channels.
2. Because it's showing everything on Peacock, it may now be possible for anyone in the world who has a good VPN to watch the US coverage, if you want to.
