A new means of releasing software

From a recent conversation with a colleague, I learned that worms have been around a lot longer than I imagined:

.                      JOHN WALKER   JANUARY 1975
.
.
. THIS PROGRAM IS A TOTALLY NEW WAY OF DISTRIBUTING VERSIONS OF
. SOFTWARE THROUGHOUT THE 1100 SERIES USER COMMUNITY.  PREVIOUS
. METHODS REQUIRED THE DELIBERATE AND PLANNED INTERCHANGE OF
. TAPES, CARD DECKS, OR OTHER TRANSFER MEDIA.  THE ADVENT OF
. 'PERVADE' PERMITS SOFTWARE TO BE RELEASED IN SUCH A MANNER THAT
. IF SOMEONE CALLS YOU UP AND ASKS FOR A VERSION OF A PROCESSOR,
. VERY LIKELY YOU CAN TELL THEM THAT THEY ALREADY HAVE IT, MUCH
. TO THEIR OWN SURPRISE.

Self replicating software a decade before the Morris worm.

Cool.
