The facts have become legend. Star Trek, the NBC series that premiered on September 8, 1966, has become a touchstone of international popular culture. It struggled through three seasons that included cancellation and last-minute revival, and turned its creator, Gene Roddenberry, into the progenitor of an intergalactic phenomenon. Eventually expanding to encompass five separate TV series, an ongoing slate of feature films, and a fan base larger than the population of many third-world countries, the Star Trek universe began not with a Big Bang but with a cautious experiment in network TV programming. Even before its premiere episode ("The Man Trap") was aired, Star Trek had struggled to attain warp-drive velocity, barely making it into the fall '66 NBC lineup.
