What if MGM Animation remains open?

In the beginning, Metro-Goldwyn-Mayer (MGM) founded its first animation house in 1937, which was responsible with many classic animated cartoons during the the Golden Age of Animation, including such introducing its library of several of the most beloved animated characters, like Tom and Jerry, Droopy, Screwball Squirrel, George and Junior, and Barney Bear.

Five years later, after MGM original animation studio was closing down in 1957, MGM revived its animation felicity with Warner Bros. animator Chuck Jones, under its name MGM Animation/Visual Arts, known for producing its version of the Tom and Jerry series, and as well as television specials like How the Grinch Stole Christmas, Horton Hears a Who! and the film The Phantom Tollbooth, until it, again closed down in 1970.

Up to the 1990s, MGM rebooted its animation arm with Metro-Goldwyn-Mayer Animation, who would produced mostly direct-to-video animated movies and television programs, with one occasional theatrical release, particularly based on MGM-owned franchises like The Pink Panther and All Dogs Go to Heaven, until however, it got seemly defunct since around 2000s.

To this day, there aren't anymore animation arms run by MGM ever since, despite currently distributing third-party-produced animated films.

So with that said, let's take a time to turn on our imagination so we can learn the theory if MGM's three animation studios would be an one studio together, by thinking about what could've be like if it remained opening to this day, and also think of the differences and changes of the studio itself.
