Magazine Management, the magazine and comic-book publishing parent of Marvel Comics at the time, released a number of magazine-format comics in the 1970s, primarily from 1973 to 1977, in the market dominated by Warren Publishing. The line of mostly black-and-white anthology magazines predominantly featured horror, sword and sorcery, and science fiction. The magazines did not carry the Marvel name, but were produced by Marvel staffers and freelancers, and featured characters regularly found in Marvel comic books, as well as some creator-owned material. In addition to the many horror titles, magazines in this group included Savage Sword of Conan, The Deadly Hands of Kung Fu, Marvel Preview, and Planet of the Apes.
