What is IBM advertising there?

Probably thinkpads or some enterprise stuff.

Thinkpads were sold off to Lenovo 18 years ago.

Huh. Thought IBM owned Lenovo.

Not at all. Always been a Chinese company. And I'm just now learning that IBM sold them their server business in 2014, and they also bought Motorola in the same year.

Which raises the question: What does IBM even do anymore?
