Same here. My kids and other young people I know, have no interest in baseball. We have gone to some games, and they get bored and don’t really watch the game much.
I’ve noticed the same among other people at the ballpark too. I recall decades ago, going to ballgames, and talking baseball with fans sitting next to me. I try that today, and it becomes clear that my neighboring fans have little knowledge of the game or strategic moves being made.
Baseball may have good attendance and record revenues due to these casual fans, who go to the ballpark but aren’t really fans. If these casual fans find something else to do, baseball will be in big financial trouble.
I remember when people actually used to keep score.
Baseball is not accessible to kids who aren't head over heels passionate about it. Neighborhood games are a thing of the past, you never see kids playing a pickup game on a park diamond. Televised games take a lifetime nowdays so they don't end until well past kids bedtimes. Going to a game is expensive enough that it's an occasional treat at best for most families. And joining a league is an absurd commitment now. Kids I know who do join end up playing in tournaments every weekend from 8am to 6 or 7pm Saturday and Sunday all summer, plus night games and practices all week. It's like you have to love baseball more than anything in the world because that's all you get to do for months on end. Most kids don't love it that much, unfortunately for the sport.
