IBM was by far the largest IT company of the day and came up with this long-range plan called SAA (Systems Applications Architecture).

SAA tied together all IBM's enterprise systems (except the Unix ones) and it mandated IBM's version of OS/2 on the client.

Some people felt that IBM had sufficient market power to impose it. I assume Lotus did, too. It turned out that IBM was wrong, and Lotus's strategy sank along with IBM's.

OS/2 was part of a strategy to take back control of the PC industry by shifting the whole thing to an IBM-controlled base with PS/2 systems, MCA buses, and the OS/2 operating system.
