I was at Illinois during 1992-1997. The school had a number of gopher services, and then ... poof, Mosaic. I think we set up our research group's http server in 1994. One of the PIs wanted to support both gopher and http, but by then the writing was already clearly on the wall, and we only did http.

There are some gopher diehards about. http://gopher.floodgap.com/gopher/gw . The relevant Wikipedia page says 'In February 2022 Veronica indexed 325 gopher servers.'
