NeXTSTEP, a computer operating system launched by Steve Jobs after he was forced out of Apple, celebrated its 35th anniversary on September 18, 1989, and though it has been discontinued, it's had a monumental impact on computing history and development.
It was NeXTSTEP that paved the way for macOS and all of Apple's other modern operating systems, and in addition, the World Wide Web was dreamed up on it as well.
The macOS Dock, large full-color icons, drag-and-drop functionality across the operating system, scrolling and window dragging, properties dialog boxes, and keyboard shortcuts are some of the things that NeXTSTEP was responsible for.
The Electronic AppWrapper, the forerunner of modern app stores, was created on NeXTSTEP. It was a catalog for distributing apps, music, fonts, clip art, and other software, well ahead of its time.
NeXTSTEP's power made it an excellent resource for programmers and app developers. It found its way to CERN, the nuclear research organization, and helped computer scientist Tim Berners-Lee to create the World Wide Web.
Berners-Lee also used NeXTSTEP to develop the world's first web browser, which he named WorldWideWeb. The popular games Doom and Quake were also created on the system.
The legacy of NeXTSTEP lives on in terms of software features still in use and the things it was used to create, even though it remains relatively unknown.
Apple formally bought NeXT in 1997 for $429 million, bringing Steve Jobs onboard and eventually leading to the first launch of Mac OS X, ending active development of NeXT's operating system.
Despite its small sales numbers, NeXTSTEP had an outsized influence on computing and was held up as a trendsetter for its many innovations, with other companies quickly copying its ideas in their own systems.
The combination of NeXTSTEP and Apple's existing software led to the first launch of Mac OS X, ending active development of NeXT's operating system, and bringing about Apple's resurgence as a global rockstar.
