Seems like a case of winners write the history books.
Hey, I'm just trying to pass on my best understanding as I saw it at the time,
and in retrospect. If you're not interested, I'm happy to stop.
There were corporate and public access networks long
before TCP was set
in stone as a dominant protocol.
Sure, there were lots of alternatives (BITNET, HEPNET, SPAN, CSNET, along with
commercial systems like TYMNET and TELENET, along with a host of others whose
names now escape me). And that's just the US; Europe had an alphabet soup of its
own.
But _very_ early on (1 Jan 1983), DARPA made all their fundees (which included
all the top CS departments across the US) convert to TCP/IP. (NCP was turned
off on the ARPANET,and everyone was forced to switch over, or get off the
network.) A couple of other things went for TCP/IP too (e.g. NSF's
super-computer network). A Federal ad hoc inter-departmental committee called
the FRICC moved others (e.g. NASA and DoE) in the direction of TCP/IP,
too.
That's what created the large user community that eventually drove all the
others out of business. (Metcalfe's Law.)
