Source? That's sure not the way I remember it. I don't think I ever saw OS/2 outside of in computer stores. I don't think I ever saw a single customer actually using it, either professionally or on a home computer.
Sure, that's anecdote. Do you have data?
Nah, no data. Too lazy to dig around. I vividly remember that in my bubble OS/2 was running everywhere. Literally everybody used it, me included. We considered Windows a joke. Some networking software that we used (Fidonet) was literally OS/2 only.
But then I remember how OS/2 was dying a slow death while Windows 95 rose.
So yes, an anecdote it is.
OS/2 was somewhat popular in corporate settings that were already "IBM shops." And I saw a bit of it in academia/scientific workplaces.
Never knew anyone who ran it at home.
