TokenRing was already an academic curiosity when I was getting my CS degree in the mid-90s. The CS department by that point had already switched to twisted-pair Ethernet. By the time of my first job in the late 90s, we used FDDI for our web farm's backend network, but we tore that out with the arrival of gigabit, so FDDI didn't last too long either.
Token Ring topology was included in Microsoft's Networking Essentials certification at least as late as 2000. I started my first tech job in 1998 at a large bank and they still had production token ring networks.
