Comic book publishers are companies that produce and distribute comic books, which are illustrated stories often featuring superheroes, fantasy, or adventure themes. Some of the most well-known publishers include Marvel Comics and DC Comics, both of which have created iconic characters like Spider-Man and Batman. These publishers work with writers, artists, and editors to develop engaging stories and artwork. In addition to traditional print comics, many publishers are now exploring digital formats, allowing readers to access comics online or through apps. This shift has expanded the audience for comic books, making them more accessible to fans around the world.
