IBM did a lot of pretty fragmented and often PR-adjacent work. And getting into some industry-specific (e.g. healthcare) things that didn't really work out. But my understanding is that it's better standardized and embedded in products these days.
Not to be rude, but that didn't answer my question.
Taking a look at IBM's Watson page, https://www.ibm.com/watson, it appears to me that they basically started over with "watsonx" in 2023 (after ChatGPT was released) and what's there now is basically just a hat tip to their previous branding.
I think that's essentially accurate even if some work from IBM Research in particular did carry over. As I recall my timelines, yes, IBM rebooted and reorganized Watson to a significant degree while continuing to use a derivation of the original branding (and took advantage of Red Hat platforms/products).
