It is very misleading or outright perverse to write "they were selling software as a service in the IBM 360 days" when there was no public network that could be used to the deliver the service. (There were wide-area networks, but each one was used by a single organization and possibly a few of its most important customers and suppliers, hence the qualifier "public" above.)

But anyways, my question to you is, was there any software that IBM charged money for as opposed to providing the software at no additional cost with the purchase or rental of a computer?

I do know that no one sold software software (i.e., commercial off-the-shelf software) in the 1960s: the legal framework that allowed software owners to bring lawsuits for copyright violations appeared in the early 1980s.

There was an organization named SHARE composed of customers of IBM whereby one customer could obtain software written by other other customers (much like the open-source ecosystem) but I don't recall money ever changing hands for any of this software except a very minimal fee (orders of magnitude lower than the rental or purchase price of a System/360, which started at about $660,000 in 2025 dollars).

Also, IIUC most owners or renters of a System/360 had to employ programmers to adapt the software IBM provided. There is software with that quality these days, too (.e.g, ERP software for large enterprises) but no one calls that a software as a service.

Hardware was part of the service, obviously.
