IBM had its own OSes the descendant of which is z/OS (check out the mother of all demos). Unix came about in the early 70s on PDPs and later many other computers. IBM/MS DOS (later Windows) also appeared, but it was never popular with most programmers.

What languages?
System programming - assembly, later C.
Science - Fortran, later C
Accounting - COBOL, later awk
Application - Assembly, Fortran, later Pascal, C, C++, Java
OOP - Simula -> Smalltalk -> C++ -> Java
