Counterpoint: while MLB has the highest total it is no longer “The Sport” and the NFL has taken over in cultural significance.

For example the MLB World Series avg viewership for 2022 was about 12 million. The average viewership for a Regular Season NFL game is 17 million.

So more people watch NFL games that may or may not be competing for playoff seeding or have the best teams in the league/be in the best time slots or even broadcasted nationally. The World Series is a national broadcast and still falls short.

There is a reason why the tv rights for the NFL dominate every other league. More people care to spend their time watching games. And any game for the NFL when compared to the playoffs or championship of other sports.
