 Jointly developed by
Microsoft Corp. and IBM to operate
with Intel Corp.'s
microprocessors, OS/2 was originally a 16-bit operating system that was designed to work with
286
processors and first introduced in 1987. Today, OS/2 is a
graphical interface similar to Windows; however, it can also be run through
command-line entries, such as DOS. In fact, many OS/2 and DOS commands
are the same.
In 1992, a new
32-bit version was released to operate with
386 and above PCs and at this time was
now solely an IBM product. Later in 1994, IBM released a version it called OS/2 Warp
that included Internet access and additional features. At the same time Microsoft was working on OS/2
version 3.0; however, it later became Microsoft Windows NT.
OS/2 never became as popular as the other Microsoft operating systems, and software developers never created a substantial
number of programs to run primarily under OS/2. Although some computer experts say later
versions of OS/2 are superior to Windows, Windows and the number of products created for
it still dominate the market today.
IBM officially announces on July
14, 2005 that all sales of
OS/2 will end on December 23, 2005 and that all support from IBM
for OS/2 will end on December 16, 2005.
