second this - I saw TCP/IP protocol running alongside other network protocols on Ethernet cables at that time. There was fierce business competition already; the technical media usually parroted the marketing leads from the various companies. Within technical academia (ivory tower) and close dot-mil (ARPA) they didn't make much of a public msg, so Byte Magazine readers didn't hear that terminology. Here in California, I never heard anyone say "Internet Protocol" in those days, not once.
