Gopher is an Internet environment and protocol similar to the Web
and HTTP. Gopher predates the Web; one could say that Gopher kind
of "gave birth" to it. Most Web browsers still support browsing
Gopherspace to a certain extent (although IE is NOT reccommended).
Gopher pages kind of look like this page (that is, when you look
at them using Gnopher with the default theme. To see other themes
check out our Website theme selector.)
