"Linux" as a operating system distribution (which includes the kernel as created by Linus Torvalds), was in some way influenced by Unix (this includes Apple's Mac OS and OS X, which was based on BSD, which was derived from Unix) at some point in their development.

For PCs, MS-DOS came before Windows. Other platforms had CPM, Unix, or their own OS they called DOS. Some had no operating system at all, just some BIOS routines and built-in BASIC, and any software pretty much having to write what bit of OS they needed. Even early PCs could be run without an OS if the BASIC ROM was installed.
