(written from a Production point of view)
Schuster & Schuster, Psi Fi Movie Press, Movie Publisher Services, Pioneer Books, New Media Books, New Media Publishing, Inc., and Couch Potato Inc. were a series of imprints of the publishing company formed by Hal Schuster in the United States in the early-1980s through to the mid-1990s to specialize in non-fiction books about film and comic book entertainment. His brother Jack acted as President. Typically, their output was not licensed by the entities who owned the properties, but instead relied on unauthorized reflections by the participants to the production of the entertainments. They published on a wide variety of properties, including Star Trek, Batman, Michael J. Fox, and Calvin And Hobbes.
Schuster began with the publishing of the Star Trek Files Magazine series, publishing several volumes a year. Each issue was 40-60 pages in magazine form, but was bound in the style of a paperback book. Each issue was written by John Peel, Edward Gross, or James Van Hise. Most of the issues were published under the "Psi Fi Movie Press" name, but some were also published under the "New Media Books" name. A similarly-conceived magazine, Enterprise Incidents, was published under the imprint "New Media Publishing, Inc." for which, besides the above-mentioned authors, Paul Newitt also submitted articles. Contrary to what the name suggested, articles about other science fiction productions were also included in that publication.
After a few years, this approach was changed to larger compilation books. These compilations contained some material from the prior Star Trek Files Magazine issues along with some new material. The company names changed with each revision, and books under the "Pioneer" umbrella were even distributed to regular bookstores.
One of their unusual forays into the world of fiction publishing sparked controversy in that author Jean Airey claimed that they never had permission to publish a substantively altered version of her work, The Doctor and the Enterprise.
