MTM Enterprises was the American television production company founded in 1969 by Mary Tyler Moore and Grant Tinker, known for shows including The Mary Tyler Moore Show and Hill Street Blues. Its closing logo used Mimsie the cat in a circular ribbon frame, a direct parody of the MGM lion, and the meow became instantly recognisable to TV viewers. Spoof edits and lamp versions circulated on meme soundboards, keeping the joke alive alongside later logo sounds like the Netflix intro that audiences now quote as shorthand for a show ending.
