OMNI was launched (PDF) by Kathy Keeton, long-time companion and later wife of Penthouse magazine publisher Bob Guccione, who described the magazine in its first issue as "an original if not controversial mixture of science fact, fiction, fantasy and the paranormal". OMNI developed a dual personality during its life. In its early run, its high circulation (permitting payment for stories many times higher than that of other science fiction magazines), coupled with some outstanding fiction editors, allowed it to attract prominent sf and fantasy writers, and it published a number of stories that have become genre classics, such as Orson Scott Card's "Unaccompanied Sonata", William Gibson's "Burning Chrome" and "Johnny Mnemonic", Harlan Ellison's novella "Mefisto in Onyx", and George R. R. Martin's "Sandkings". The magazine also published original sf/f by William S. Burroughs, Joyce Carol Oates, Jonathan Carroll, T. Coraghessan Boyle, and other mainstream writers. The magazine excerpted Stephen King's novel Firestarter, and featured a short story, "The End of the Whole Mess". OMNI also brought the works of numerous painters to the attention of a large audience, such as H.R. Giger, De Es Schwertberger and Rallé.
