Mathematica has had pretty advanced programmer notebooks for something like 20 years i think. Jupyter definitely isn't new. The only new part would be a lot of languages (Python, Julia...etc) starting to use it.

I think spreadsheets came out earlier: https://en.wikipedia.org/wiki/Spreadsheet says 1969 for a commercial product.

Basically they're "just" a declarative data-flow system. Similar timeframe, but slightly earlier, at least as far as my wikipedia-fu is suggesting[1], in the 60s.

But yeah, they've been awfully transformative after that, and continue to be. I can't really think of a better counter-example at the moment.

Off the top of my head:

* type inference

* message passing concurrency
