IBM has largely retreated from consumer facing ventures but it's still a behemoth.

From the start of its Wikipedia page:

> IBM is the largest industrial research organization in the world, with 19 research facilities across a dozen countries, having held the record for most annual U.S. patents generated by a business for 29 consecutive years from 1993 to 2021.

I know that in semiconductors they're still doing bleeding edge R&D which they then try to license to foundries. Their mainframe business is still doing quite well too.

And I'm sure they're active in many other niches that I know little about.
