NeWS (
Network extensible Window System) was a
windowing system developed by
Sun Microsystems in the mid-1980s. Originally known as "SunDew", its primary authors were
James Gosling and
David S. H. Rosenthal. The NeWS
interpreter was based on
PostScript (as was the later
Display PostScript, although the two projects were otherwise unrelated) extending it to allow interaction and multiple "contexts" to support windows. Like PostScript, NeWS could be used as a complete programming language, but unlike PostScript, NeWS could be used to make complete interactive programs with mouse support and a
GUI.
