In the TCP/IP world, that would most likely come from the terminology
of the PDP-10 world (think back to the days of IMPs, etc.)  On the -10,
one stores 6 6-bit characters in a machine word, and one speaks of
bytes that are 6 bits.  AFAIK, 'octet' was invented in networking circles
to prevent any ambiguity about which size byte one was discussing.

Outside of PDP-10 and Cyber circles, "byte" has pretty much meant 8-bits,
though.  If one only worked on microcomputers (i.e., post 1974), the
tug-of-war was over, and byte "always meant 8 bits".
