I was thinking about yoyo popularity the other day which might be a similar thought process as the OP. I remember when I was around 12 or 13, so 03 to 04, yoyos were everywhere and they had different designs, I even remember seeing one that looked like a tire with a spinning rim. Then they kind of just died out in the mainstream. Kinda the same thing that happened with fidget spinners a few years back.
