The Open Firmware bootloader also used a Forth as its command-line interface. That was used on PowerPC Macs before Apple switched over to Intel. (So, you know, two processor architectures ago.)

A common theme is that Forth-likes are very easy to implement on constrained hardware. I have a Strange Loop talk a couple of years ago where I go into this at the end, calling out uxn from the Hundred Rabbits folks. You might consider that more "hobbyist" than "production", but people are deriving real joy making apps and games in that ecosystem.

For a counterargument, this is the most commonly cited argument that I've seen _against_ using a Forth-like in an industrial context:
