When you are on a college team, coaching, leotards, transportation, etc are all provided. But NCAA gymnastics (and the coaches) have done a LOT of work to make the sport more popular. I remember when I started going (as a baby in her mothers arms

) to watch NCAA gymnastics in 1985. There was a curtain over half the arena so people couldn't see how empty it was. But the coaches had posters and calendars made up and had the athletes out signing them and out and about town so people could see them. That made it a little more popular. But it was still so hard to follow, I might get 1 or 2 comps per year on TV, and I was living in an area with no NCAA team.
THEN, SEC network arrived as well as Big 10 Network plus and some programs, such as BYU, stream live on their own app. Now it is extremely popular, there are cheerleaders, mascots, fireworks, sold out crowds....So there are ways...but one needs to find niche networks for niche sports. And I think the paralympic swimming was on Peacock for a week! Is paralympic swimming THAT popular? Also the other streaming services in US are now offering sports streaming...Paramount Plus...Amazon...etc.
