DC and Marvel Comics have stood as the two titans of the comic book industry for more than 50 years and, like a superhero squaring off against his nemesis, the two have spent much of that time battling one another for dominance. In his new book Slugfest: Inside the Epic, 50-year Battle between Marvel and DC, journalist Reed Tucker goes inside this corporate rivalry and explores how each company has tried to outmaneuver one another in whatever way possible: from stealing ideas to copying one another to launching price wars.
