It's a failed article IMHO. It's to the point that the article should be pulled and corrected. None, as in zero TVs are made in the USA. They haven't been made in the USA for many decades. I HATE to say it, but an LLM would have given a better researched article.
While reading the article, I was pretty suspicious about Emerson and Westinghouse, because they sound just like Polaroid - once a solid American manufacturer, but run into the ground and then the name is licensed to bottom-of-the-barrel cheap electronics marketers. It seems strange that the article went out of its way to mention they are headquartered in Pittsburg and founded in the 1940s, like it's some respected brand with a long tradition.
That said my Dynex TV from like 2008 won't die so my agreement with my wife to replace it can't kick in for a 75" OLED TV...someday. Thing has a decent panel FHD and 120hz and you can turn the smoothing crap off and it's definitely a dumb TV

Westinghouse TVs are made by a company licensing the brand, not a "Pittsburgh-headquartered company".
These seem like easy mistakes to avoid.
