Well Marvel didn't cancel the original Spider-Man comic and just have the close-to-the-movies Ultimate version after the Raimi film was released even though the movies had a bigger audience.
Yet, they’ve now cancelled Ultimates. And combined a lot of its elements with the normal comics, apparently in effort to be closer to the movies.
Because Ultimates was no longer financially viable enough to justify its somewhat confusing existence, versus the appeal of trying to net in new readers. Legends apparently ended up in the same boat.
Oh well.
