What happened to TAB Books?

Factual Questions
1

Does anyone know what happened to TAB Books? They used to publish thousands of “do it yourself” tech books and now they appear to have disappeared. I can’t find any trace of them or any heir or assign on the web.

They even published a couple of my books back in the day, not that I ever saw a dime past the paltry advances. I’m just surprised they disappeared so thoroughly.

They’re still around. They’re an imprint of McGraw-Hill, and mainly went digital.

I see. Looks like a “closet” imprint; no real resources or staff, just haul the box out of the storage closet occasionally. They don’t even have a web page or functioning domain, just tippy-toe social media presence.

Oh, well.
