There is a world cup circuit, but watching it takes effort. Ski jump is another one that is hard to watch, hard to find training, and hardest of all to have the physical body type required to be successful. You aren’t getting into that one unless you live next door to the hill or have a parent who did it or pushing you into it.
But even popular events like short track speed skating disappear off the tv in the us apart from the olympics. Or are shown on such an obscure channel as to be disappeared.
The barriers to entry for summer sports are definitely lower.
