I assume that Marvel isn't far behind.
Marvel has enough money to float an entire comic book division just for appearances sake to support the movies.
DC was doomed from the moment it was bought out by Time-Warner 50 years ago. It was just a slow motion doom.
There’s still a lot of $$ for Time-Warner to earn via movies. Wonder Woman 1984 has been ready to go for a long time, but its release keeps getting delayed because of the pandemic. Will they get max profit from movies after ceasing publishing of comic mags? I don’t think so. That would alienate a lot of fans.
