The Star Trek media franchise is a multibillion dollar industry, owned by Paramount Global. Gene Roddenberry sold Star Trek to NBC as a classic adventure drama; he pitched the show as "Wagon Train to the Stars" and as Horatio Hornblower in Space. The opening line, "to boldly go where no man has gone before", was taken almost verbatim from a U.S. White House booklet on space produced after the Sputnik flight in 1957.

Star Trek and its spin-offs have proven highly popular in syndication and was broadcast worldwide. The show's cultural impact goes far beyond its longevity and profitability. Star Trek conventions have become popular among its fans, who call themselves "trekkies" or "trekkers". An entire subculture has grown up around the franchise, which was documented in the film Trekkies. Star Trek was ranked most popular cult show by TV Guide. The franchise has also garnered many comparisons of the Star Wars franchise being rivals in the science fiction genre with many fans and scholars.

The Star Trek franchise inspired some designers of technologies, the Palm PDA and the handheld mobile phone. Michael Jones, Chief technologist of Google Earth, has cited the tricorder's mapping capability as one inspiration in the development of Keyhole / Google Earth. The Tricorder X Prize, a contest to build a medical tricorder device was announced in 2012. Ten finalists were selected in 2014, and the winner was to be selected in January 2016. However, no team managed to reach all the required criteria; smaller prizes were given to three of the finalists. Star Trek also brought teleportation to popular attention with its depiction of "matter-energy transport", with the famously misquoted phrase "Beam me up, Scotty" entering the vernacular. The Star Trek replicator is credited in the scientific literature with inspiring the field of diatom nanotechnology. In 1976, following a letter writing campaign, NASA named its prototype Space Shuttle Enterprise, after the fictional starship. Later, the introductory sequence to Star Trek: Enterprise included footage of this shuttle which, along with images of a naval sailing vessel called Enterprise, depicted the advancement of human transportation technology.
