This Day in History: 22Aug1955, The First Computer User Group Is Founded
http://www.computerhistory.org/tdih/August/22/

Following a Los Angeles symposium hosted by IBM, a group of
representatives from seventeen groups that had ordered the IBM 704
mainframe computer met at the RAND Corporation in Santa Monica,
California. The outcome of the meeting was the first computer user's
group, SHARE. The name was chosen to promote the idea of sharing
information and programs between installations. The group grew quickly,
eventually producing new software and documentation for their IBM
computers.

23Jun1969 unbundling announcement ... that started to charge for
(application) software. Company was able to make the case that operating
system software should still be free. some past posts

Then the "Future System" effort in the early/mid 70s ... was completely
different and replace 370 ... so 370 efforts were being shutdown ...
the lack of 370 products during the period is credited with giving clone
processor makers a market foothold. more discussion

when Future System imploded, there was mad rush to get products back
into the 370 pipeline ... and also because of the clone processors
... decision to transition to charging for operating system software.
