Historically (i.e. going back to the 1970's) there have been many operating systems for the mainframe. At that time there were several companies (IBM, ICL, Siemens, Fujitsu, GEC, etc) making mainframes and each had it's own operating system. Today there is only one manufacturer still in this very lucrative market - IBM. IBM has had several mainframe operating systems - today they have three still in use - the main and most powerful one is z/OS (often referred to as MVS), the other two are z/VM and VSE/E.
