IBM OS/2: Operating System

Discontinued operating system created by IBM & Microsoft, alternative to Windows & Mac OS, innovative features, but failed to gain popularity

What is IBM OS/2?

IBM OS/2 is a discontinued operating system that was originally developed in the late 1980s through a collaboration between technology giants IBM and Microsoft. The goal was to create a robust, object-oriented successor to DOS that could compete with Apple's Macintosh platform and the early versions of Microsoft Windows.

OS/2 introduced several innovations, including preemptive multitasking, Workplace Shell GUI, PowerPC microprocessor support, and built-in networking capabilities. It offered stability, security, and compatibility with DOS and Windows applications. Over its lifespan, OS/2 ran on PCs with x86 and x64 processors.

Despite some initial success and adoption by large corporations, OS/2 failed to gain traction in the personal computing market. Reasons cited include poor marketing by IBM, competition from Microsoft Windows, lack of games and third-party applications, and hardware compatibility issues. Its last version - OS/2 Warp 4 - was released in 1996. IBM ended support for OS/2 in 2006.

OS/2 still maintains a cult following of dedicated users who praise its technical merits, robustness and security features. But for most computing tasks, OS/2 has been replaced by various flavors of Windows, Linux and macOS operating systems over the past two decades.
