Why Didn't DreamWorks succeed to stay a major studio

The Reason Why Didn't DreamWorks succeed to stay a major studio is that DreamWorks Animation SKG became spin-off in 2004.

DreamWorks is once a major studio when Manhattan Pictures and it's 6,000 film library is bought. DreamWorks is the second-largest library owner in the world behind Warner Bros., but in 2006, DreamWorks Animation bought Manhattan's 6,000 film library from Viacom.

after Comcast bought DreamWorks in 2016, the Shaw Brothers library were no longer part of the DreamWorks library. until 2022, Universal is the Largest library owner in the World.

since 2022, American Greetings it the Largest Movie Studio and Library Owner in the World.
