We still haven't come up with a decent answer, imo. Changing to ?? ??
I'm sure you're right about video games and such, but from where I sit, I just see sports changing. I've always been into "non-sport sports" - rock climbing, trail running, backcountry skiing, things like that. When I was younger, these were all fringe sports. As recently as 2000, it was hard to even find a decent selection of backcountry ski gear in the US. I was having my gear shipped from Europe.
Now, it's an exploding market and you can't buy that sh## at Sports Authority.
Same with rock climbing. Before the mid-1990s, it was sort of fringe. Then it got popular in gyms. But in the last few years it has utterly changed. People like Alex Honnold can pull down big enough bucks to start *foundations*. In 2000, sponsored climbers who got paid enough to buy a new van could be counted on your hands.
In my little "adventure sports" corner of the world, things are booming to the point that the resources we use to enjoy our sports are being stretched.
