I have a real "ultimate" disc I bought as a fundraiser for a university team. Its amazing how well it flies compared to the cheap light disks. (Its heavy but really goes).
My other favorite is the aerobie "super disk". Its not the ring like disk, but more like a "frisbee" disk. I play with my nieces and its easier to throw and has a kind of softer outer ring so easier to catch.
Fun fact - the popular coffee maker AeroPress was also borne out of Aerobie.
It's interesting how recreational activities can go out of style for no particular reason. Rollerblades/inline skates is another one in the US. It was popular for a period and you rarely see anyone skating any longer.
ADDED: As you and others note, I guess disc golf is actually a fairly big thing although I confess I've never actually played it.
You can get an Innova starter set for around $20 at your local sporting goods store, and those 3 discs can/will last you a long, long time. Once you buy your first non-starter set disc, you may become addicted to buying discs you'll never throw, haha.
Most of that feels like a very extreme sports lens on the topic though. My experience of rollerblading was as mostly a 30 something where a bunch of us would do evening skates on the bike path or on paved paths in the city and park, etc. At the end of the day, something he says at the end of the video is probably right. It was a fad and once enough people grew out of it or just stopped doing it as much, the network effect of it being an activity to do with friends decreased.
You see them less in populated parks, because you need a bit more space to be safe with them than, say, a nerf football or tennis ball.
I played ultimate in college, a decade or two ago, and it was a huge and growing sport.
Disc golf now is one of the faster growing sports in the us, full stop.

I probably go with fashion/fad at the end of the day.
