It depends what you mean by widely used and PC. The widely used Apple II computer used Apple DOS while another operating system which was widely adopted (including versions for the Apple II) was called CP/M which was created by Digital Research. They went on to create DR-DOS which was one of the versions of DOS used on the early IBM personal computers. Microsoft had purchased an operating system called QDOS which was adapted by IBM into PC-DOS for their own computers and by Microsoft as MS-DOS for use on computers not made by IBM but following their design (known as IBM clones). These became increasingly popular and so MS-DOS became widely adopted and PC-DOS faded away. Apple went on to develop the Macintosh with its graphical user interface which Microsoft copied to create their Windows operating system.
