What happened to plasma TVs? Can you still buy one?

It’s not uncommon for people to gloss over evolutionary steps in technology, and I have to admit, even I’m guilty of that sometimes. Lately I’ve been touching on the development of TVs over the years, including LCD, OLED, and mini-LED panels, but I almost forgot about the existence of a format that was once state-of-the-art: plasma. That’s strange, in a sense, because I remember a brief time when the word “plasma” had a distinct cachet among TV shoppers.
