Last I'd heard, Zenith had been taken over by Gold Star after bankruptcy troubles. There IS an American owned TV manufacturer in Kentucky, I believe, which makes sets for various famous brand names. If they'd not fought and won a federal lawsuit accusing Chinese manufacturers of dumping their products, even this company would have folded. I saw this on a PBS special about Wal-Mart about two months ago.
