NeXTSTEP is the original object-oriented, multitasking operating system that NeXT Computer, Inc. developed to run on i
- a [[Unix-ln of the OpenStep standard, which resulted in Mac OS X. Mac OS X's OpenStep heritage can be seen in the Cocoa development environment, where the Objective-C library objects have "NS" prefixes. A free software implementation of the OpenStep standard, GNUstep, also exists.
The first web browser, WorldWideWeb, was developed on the NeXTSTEP platform. Some features and keyboard shortcuts now commonly found in web browsers can be traced to originally being native features of NeXTSTEP, which other web browsers for other operating systems later reimplemented as features of the browser itself. The game DOOM was also largely developed on NeXT machines, as was Macromedia FreeHand, the modern "Notebook" interface for Mathematica, and the advanced spreadsheet Lotus Improv.
