What? SNF is doing OK. 2021 was an anomaly for broadcast TV. Production was shutdown due to Covid. The NFL is transitioning to streaming, as well as broadcast.
They’re not going away anytime soon…. Unless the lawyers do it
The NFL draws well compared to other television shows but does not draw well compared to the NFL of the past. Worse, with an additional 70 million more people today (247 million then, compared to 315 million now), the NFL still can't hit their previous numbers.
While the decline of NFL viewership may continue for years, television as a whole is approaching the threshold where it costs more to run a network than the amount of money that can be made from it. Subsidies from governments that are $200+ trillion in the hole, and legalized gambling aren't going to be enough to keep it afloat.
As evidenced by the takeover of streaming and requiring subscriptions of "Sunday ticket" for pay-per-season-viewing, the NFL will be forced fully onto its own medium, leaving the carcass of television behind. As that happens, advertisers will continue to find other options.
