Industry did adopt ALGOL variants, it was and still is, one of the languages on the Burroughs linage.

UK Navy also had a system programmed on it.

Also it was largely influential in PL/I and its dialects, which were used a bit everywhere, the most well known being PL.8, PL/S and PL/M.

And the competition that eventually lead to the Pascal tree of programming languages.

History would have been much different if Algol 68 hadn't existed in first place.
