The PDP-6 is the origin of the architecture. It was announced in March 1964 in
Business Week, 3 weeks before the announcement of the IBM System/360 in April.
First customer ship of the PDP-6 was in June 1964; FCS of the System/360 was in
October 1965.

The original definition of a byte, in signal processing, was "a collection of
bits", and had nothing to do with characters, or memory words.
The PDP-6 usage of the term is based on that original definition.

No one ever said that was addressable at the character level!

They were called "characters", as were 6 bit entities.

That is also the format for ASCII text in the DEC operating systems for the
PDP-6 (on which ITS originally ran) and PDP-10. Nothing special about MIT
here.
And the 7 bit entities treated as ASCII characters are called "bytes" when
manipulating them with byte pointers in the relevant instructions.
