Thanks for the link! The bits I was aware of (/lived through), from UX standpoint was: Mathematica -> iPython notebooks -> jupyter notebooks. And from whatever source, I knew Mathematica notebooks had looked how they had /at least/ since the mid 90s. (My Mathematica days were college, and I did not spend much time contemplating the history of my tooling) From elsewhere in the comments, it sounds like iPython->jupyter wasn't just a rebranding, as I assumed it was at the time.
