I knew they were the first, but since longboarding died out in the 90's and early 2000's, they've been making a comeback. They're still going to get larger, but for the time being freeride and downhill are most popular.
Yeah man its a collection of other people's opinion you are supposed to go through and sort out who to follow and just so you know freestyle dancing and slalom were the first but I'm not here to correct you. freeride is the newest btw
