(written from a Production point of view)
Star Trek Interstellar: The Official Star Trek Fan Club was the first officially authorized fan club for the Star Trek franchise and was established by Gene Roddenberry in 1968. Initially, Ruth Berman edited the club's publications and co-ordinated the fan club on behalf of "Star Trek Enterprises", Roddenberry's merchandising company that was later renamed "Lincoln Enterprises".
The fan club published twelve issues of Inside Star Trek and enjoyed close access to Star Trek: The Original Series' cast and crew during the production of the series' third season. Following the show's cancellation by NBC in 1969, both the club and the magazine were discontinued.
