SAN DIEGO — To survive in the brave new digital world, writer Grant Morrison thinks comic books need to get back to what the medium does best: big ideas.

Morrison stopped by the Wired Cafe during Comic-Con International to discuss an industry’s struggling for direction in an era of declining print sales. He also holds forth on the place of superheroes in the modern world, a topic he explores in his new comic book history book, Supergods.
