<random anecdote>
This is true, but I think the market example is

OSI never really got any real deployment, is was just
a proposal when both were nascent. SNA was well
deployed prior to TCP/IP and APPN was hailed
(at least by the SNA bigots I knew) to be the
thing that fended off the TCP/IP push for good.
(in business networks)
Ultimately, while SNA still exists for legacy
systems, very few new SNA deployments are happening,
instead being TCP/IP ones. The part I find most
amusing is that the most common method of expanding
SNA networks is via IP routers which do DLSw.
(a protocol which tunnels SNA over IP to create
SNA "WANS", SNA traditionally was bridged...)
