American Gambling Association estimates NFL bring in several billion with a B in additional revenue from legalized sports betting from sponsorships and increased interest. The ratings back that up and the idea that swifties are helping as well. While I'm sure Seems is probably joking, there are estimates out there that there were around 2 million extra eyeballs in 2023 watching the games from swifties alone. One estimate had the NFL raking in over 300 million from this including sponsorships (there were quite a few more ads aimed at women this year for some reason) and extra sales of sponsored items.
