In terms of their library, they do have enough to rival Disney, but in terms of how big they are as a brand, there’s simply no comparison. Disney is a household name that is home to Walt Disney Animation, Pixar, Marvel, Star Wars, and as of 2019, The Simpsons. Sure, Warner Media owns plenty of beloved classics, but in terms of big money-making properties with wide appeal, no studio can beat Disney.
At the very least, I’ll say this much, at least WB/HBO is a bigger brand name than Paramount. Seriously, ‘Paramount+’? That is just plain ridiculous.
