Metro-Goldwyn-Mayer
From Muppet Wiki
Metro-Goldwyn-Mayer (a.k.a. MGM) is a movie distributor. Currently, a majority stake of the studio is owned by the Sony Corporation of America, which also owns Columbia Pictures and TriStar Pictures, although it distributes its home-video releases through 20th Century Fox.
The studio became famous for its mascot Leo the Lion, whose roar opened each film with the exception of 2001: A Space Odyssey. This was spoofed by Animal in The Great Muppet Caper, and by Fozzie Bear in The Muppets Go to the Movies.
