They are still around and still as bad as ever. I believe the company is based in Detroit, as their founder was/still is the owner of the Detroit Tigers and Red Wings. You see their advertisements throughout their respective stadium/arena.
What’s interesting to me is that Illitch, one of the current owners of the Tigers, was preceeded by Tom Monaghan, who owned them from 1983-1992. Monaghan founded Dominos.
