It was used on Unix systems even before that.

definitely used something similar on VAX/VMS called VMS_SHARE (https://www.glaver.org/ftp/multinet-contributed-software/vms...) circa '90-91

in fact I found an old archive of mine floating around on usenet and wrote a python script to unpack it. Looking at the original, it was using a scripting. language bootstrap to make a COM script unpack embedded the original code.

Lots of commercial Linux software use this still for installing their stuff. It’s a neat trick

I've seen it recently with the Conda and Mamba package managers.
