The way I remember it, IBM decided they wanted a version of CP/M for their new Intel 8086-based system and went to Digital Research. Somehow the folks at DR managed to really annoy the folks from IBM. (I heard it that Gary Kildall's wife wouldn't deal with them because Gary was out-of-town.) So IBM turned to the small company that was supposed to provide the BASIC interpreter for the new "PC": Microsoft.

Bill Gates of Microsoft assured IBM that Microsoft had a replacement for CP/M-86 even though they really didn't. (Ah, vapor-ware has been with us for a LONG time.) Microsoft then quickly purchased the rights to a CP/M lookalike called QDOS. That became IBM's PC-DOS which Microsoft then renamed MS-DOS. The rest is history.
