tkWWW was an early web browser and WYSIWYG HTML editor written by Joseph Wang at MIT as part of Project Athena and the Globewide Network Academy project. The browser was based on the Tcl language and the Tk (toolkit) extension but did not achieve broad user-acceptance or market share, although it was included in many Linux distributions by default. Joseph Wang wanted tkWWW to become a replacement for r r n and to become a "swiss army knife" of networked computing.
