I believe that the .EXE format for executables was introduced by TENEX, the BBN
operating system for the PDP-10 with attached BBN pager, for experiments in
demand-paged virtual memory.

(TOPS-20 was DEC's development of TENEX, with appropriate licensing.  Think VSI.)

The .EXE format was ported to Tops-10 later; TOPS-20 was introduced in 1974/5.
