(written from a Production point of view)
Enterprise Incidents was a magazine that began as a Star Trek fanzine and transitioned to a semi-professional magazine from issue ten (1982) onward,  when it was acquired by Hal Schuster under the imprint New Media Publishing, Inc., serving as the cornerstone of his later publishing conglomerate Schuster & Schuster. To indicate new ownership, an additional "NMP" logo was henceforth also featured on the magazine covers.
Edited by James Van Hise and begun in 1976, with regular contributions from reporters Paul Newitt and Dennis Fischer, it ran for twenty-six issues under the Enterprise Incidents name only, but started to increasingly feature articles on other science fiction and fantasy franchises as well besides Star Trek, which eventually warranted its name change to "SF Movieland" with the twenty-seventh issue (published in March 1985, with that issue featuring both the old and new title) until ending altogether with issue thirty-six, in December 1988.
Retained by the new owner as editor-in-chief, Van Hise tried to emulate for his magazine the formula of its major contemporary competitor at the time, Starlog magazine, but never quite succeeded in doing so as far as commercial succes was concerned, even though his magazine, like Starlog, ran largely material provided by the studios from the time it went "pro". 
The magazine also spun off a collection titled The Best of Enterprise Incidents: The Magazine for Star Trek Fans in 1990.
