ESPN/ABC keep MNF, and will get three weeks of separate games on MNF that will air at the same time on ABC and ESPN, a Saturday doubleheader on the final week of the season and an exclusive game (International Sunday AM) on ESPN+. Also, ESPN+ will stream all of the ESPN/ABC games.
NBC keeps Sunday nights, and will be able to stream SNF on Peacock+. Peacock will also stream on exclusive game a season from 23-28, and they will have an NFL Channel with OD NFL Films content on it.
CBS gets more doubleheaders than FOX, and is able to stream local games over Paramount+.
While it sounds like FOX is getting screwed, they will could end up with the most lucrative package. FOX gets a special Christmas Day package (in select seasons), plus they get to stream local games on TUBI, their video platform. Also, the FOX Super 6 will remain as the free to play wagering game. But, the big enchilada is FOX will receive authorized sportsbook status when and if the NFL approves sportsbooks on its property. If you live in Virginia, you know how damn big the money coming in from the new sportsbooks has been,
The announcements don't even cover Sunday Ticket which is not up until after the 2022 season. Rumor is that ESPN+ really wants it, and AT&T is not willing to be exclusive any longer since they are trying to switch the company from satellite to streaming. Their satellite fleet is aging, and they don't have any plans to launch any new ones, so it appears they are moving to the streaming model in the long run.
It appears you will be able to go around your local cableco/satco in a few years for your NFL football.
