Looking at the 2010 Haskell report: most of the committee members come from 'Academia':

How is it an 'industrial' language? Haskell is the main 'academic' language for a branch of Functional Programming.

'industrial' is just another weasel word.

If you keep your head to the ground, there are quite a few companies like Facebook that use Haskell for important things in production, but it isn't the language even 50% of the company is using. I'm sure there is a lot more lisp in production, but you typically hear about the same ratio from both camps in the blogosphere.

I would guess that in a company like Facebook, 99.5% of the code they wrote is not Haskell. If they have, say, 200MLOC of code written (just a number), this would be 1MLOC...

There are companies using a bit more of Haskell in production.

Haskell lends itself pretty well to "backend"[0] work, and there are more than a few organisations using it to write servers, trading systems, and so on. It definitely fits his metric, which is "> 1000 industrial users".

[0] (Unlike applying it to the frontend, which is a comparatively less mature situation with multiple proposed solutions.)
