Sun Microsystems began developing NeWS (Network extensible Window System) as an alternative to the X Window System. NeWS was designed to be more extensible and flexible, allowing for greater customization and functionality.

James Gosling played a significant role in the development of NeWS. His contributions likely involved designing and implementing core components of the windowing system, including its event handling, graphics rendering, and programming interface. He was instrumental in its innovative design.

NeWS used PostScript as its programming language for defining window layouts, drawing graphics, and handling events. This approach allowed for a high degree of flexibility and customization. Although not widely adopted it was technically more advanced than the existing systems.
