I've read about the "hypervisor" in hardware virtualization. VMs are not my area, so I can't quite see where the term came from.
THe wikipedia article talks about how "the hardware's supervisor state was virtualized as well, allowing multiple operating systems to run concurrently in separate virtual machine contexts"
This implies that a supervisor process was virtualized.. which then probably originated a 'hyper'-visor. Is this true?

1973
The term was in use at least as early as 1973, as seen in this advert from IPS Computer Marketing Corp. in Computerworld magazine (30 May 1973 - Vol. 7, No. 22):
1970
It appears in these two 1970 papers, with one quoting the other.
Operating systems architecture, H Katzan Jr - Proceedings of the May 5-7, 1970, spring joint computer conference:
Analysis of Major Computer Operating Systems, CS McIntosh, KP Choate, WC Mittwede - 1970 - DTIC Document (PDF):
1969?
It also appears in earlier snippets in Google Books, but care must be taken as Google often has incorrect metadata. However, this 1969 description of the IBM 360/60 in Management Services, (Volumes 6-7, American Institute of Certified Public Accountants) seems possible (date check):
1966?
It may also appear in a paper by IBM: A Virtual Machine System for the 360/40 (1966) by R Adair, R Bayles, L Comeau, R Creasy, but Google Books only shows it as a result and no text. If someone has access to this paper online, perhaps they can confirm it.
