*Star Trek: The Motion Picture* was released in December 1979 and was a commercial success despite mixed reviews. The sequel, *Star Trek II: The Wrath of Khan* (1982), is widely regarded as the high point of the film series and demonstrated that the franchise could sustain narratively ambitious, emotionally powerful stories within the science fiction action framework. The film series ran through *Star Trek VI: The Undiscovered Country* (1991), Roddenberry’s last year alive.
The television revival began with *Star Trek: The Next Generation* (1987–1994), which Roddenberry co-developed and which launched a second generation of the franchise with an entirely new cast set in the same fictional universe, 78 years after the original series. *The Next Generation*’s success opened the door to a continuous production of *Star Trek* television content — *Deep Space Nine*, *Voyager*, *Enterprise*, and eventually the streaming-era productions on Paramount+ — that has continued to the present.
The specific decision that Lucille Ball made in early 1966 — to override a board vote and nod to Herbert Solow — is at the beginning of this chain. The chain extends through the third season and cancellation, through the syndication phenomenon of the 1970s, through the film series, through the television revival, and through 50-plus years of continued production and fan engagement that has made *Star Trek* one of the most durable franchises in entertainment history.
None of this was visible in 1966. What was visible was a science fiction television series with an expensive production, inconsistent ratings, an unusual cast, and a creator who was difficult to work with. The board that voted to cancel was not stupid; they were responding to real financial pressure based on real information.
