This can be quite different from the way a user finds documents on the Web. Every Gopher document has a defined format and type, and the typical user navigates through a single server-defined menu system to get to a particular document. Gopher has a more rigid structure than the free-form HTML of the Web.Gopher client functionality was quickly duplicated by the early Mosaic web browser, which subsumed its protocol.In September 2000, the University of Minnesota re-licensed its Gopher software under the GNU General Public License. Gopher expansion stagnated, to the advantage of the World Wide Web, to which CERN disclaimed ownership. Users became concerned that fees might also be charged for independent implementations. In February 1993, the University of Minnesota announced that it would charge licensing fees for the use of its implementation of the Gopher server.Several factors contributed to Gopher's stagnation: By the late 1990s, Gopher had ceased expanding. The World Wide Web was in its infancy in 1991, and Gopher services quickly became established. The University of Minnesota mascot is the gopher, a gofer is an assistant who "goes for" things, and a gopher burrows through the ground to reach a desired location. The name was coined by Anklesaria as a play on several meanings of the word "gopher". The general interest in campus-wide information systems (CWISs) in higher education at the time, and the ease of setup of Gopher servers to create an instant CWIS with links to other sites' online directories and resources, were the factors contributing to Gopher's rapid adoption. Gopher combines document hierarchies with collections of services, including WAIS, the Archie and Veronica search engines, and gateways to other information systems such as File Transfer Protocol (FTP) and Usenet.
