Star Trek
Post– Original Series rebirth (1969–1991)

After the original series was canceled, Desilu, which by then had been renamed Paramount Television, licensed the broadcast syndication rights to help recoup the production losses. Reruns began in late 1969, and by the late 1970s the series aired in over 150 domestic and 60 international markets. This helped Star Trek develop a cult following among Trekkies greater than during its original run; by 1976, the cast described Star Trek as "the most popular series in the world".

One sign of the series' growing popularity was the first Star Trek convention, which occurred on January 21–23, 1972 in New York City. Although the original expectation was that a few hundred fans would attend, several thousand turned up. Fans continue to attend similar conventions worldwide.

The series' newfound success led to the idea of reviving the franchise. Filmation with Paramount Television produced the first post–original series show, Star Trek: The Animated Series, featuring the cast of the original series reprising their roles. It ran on NBC for 22 half-hour episodes over two seasons on Saturday mornings from 1973 to 1974. Although short-lived, typical for animated productions in that time slot during that period, the series garnered the franchise's only Emmy Award in a "Best Series" category—specifically Outstanding Entertainment Children's Series; later Emmy awards for the franchise would be in technical categories. Paramount Pictures and Roddenberry began developing a new series, Star Trek: Phase II, in May 1975 in response to the franchise's newfound popularity. Work on the series ended when the proposed Paramount Television Service folded.

Following the success of the science fiction movies Star Wars and Close Encounters of the Third Kind, Paramount adapted the planned pilot episode of Phase II into the feature film Star Trek: The Motion Picture. The film opened in North America on December 7, 1979, with mixed reviews from critics. The film earned $139 million worldwide, below expectations but enough for Paramount to create a sequel. The studio forced Roddenberry to relinquish creative control of future sequels.

The success of the sequel, Star Trek II: The Wrath of Khan, reversed the fortunes of the franchise. While the sequel grossed less than the first movie, The Wrath of Khan ' s lower production costs made it net more profit. Paramount produced six Star Trek feature films between 1979 and 1991, each featuring the Original Series cast in their original roles.

In 1987, Paramount responded to the popularity of Star Trek feature films by bringing the franchise back to television with Star Trek: The Next Generation. Paramount chose to distribute the new series as a first-run syndication show rather than a network program. The series was set a century after the original, following the adventures of a new starship Enterprise with a new crew.
