Created by Gene Roddenberry, the science fiction television series Star Trek (which eventually acquired the retronym Star Trek: The Original Series) starred William Shatner as Captain KirkLeonard Nimoy as Mr. Spock, and DeForest Kelley as Dr. Leonard "Bones" McCoy aboard the fictional Federation starship USS Enterprise. The series originally aired from September 1966 through June 1969 on NBC.[1]

This is the first television series in the Star Trek franchise, and comprises 79 regular episodes over the show's three seasons, along with the show's original pilot episode, "The Cage". The episodes are listed in order by original air date,[2] which match the episode order in each season's original,[3][4][5] remastered,[6][7][8] and Blu-rayDVD[9] box sets. The original, single-disc DVD releases placed the episodes by production order, with "The Cage" on the final disc.[10] This list also includes the stardate on which the events of each episode took place within the fictional Star Trek universe.[11]

After the show's cancellationParamount Television released Star Trek to television stations as a syndication package,[12] where the series' popularity grew to become a "major phenomenon within popular culture".[13] This popularity would eventually lead the Star Trek franchise to expand its catalog to include five more television series and twelve Trekmotion pictures.

In 2006, CBS Paramount Domestic Television (now CBS Television Distribution) announced that each Original Series episode would be re-syndicated in high definition after undergoing digital remastering, including both new and enhanced visual effects.[14] (To date, the remastered episodes have only been broadcast in standard definition, though all three seasons are now available on the high-definition Blu-ray Disc format.)[15][16] The remastered episodes began with "Balance of Terror" (along with, in some markets, "Miri") during the weekend of September 16, 2006,[17] and ended with "The Cage", which aired during the weekend of May 2, 2009.[18] The remastered air dates listed below are based on the weekend each episode aired in syndication.[17]

Pilots (1964–65)[edit]Edit

Star Trek's pilot episode, "The Cage", was completed between November 1964 and January 1965,[31] and starred Jeffrey Hunter as Captain Christopher PikeMajel Barrett as Number One, and Leonard Nimoy asSpock. After the pilot was rejected by NBC as being "too cerebral" (among other complaints),[32] Jeffrey Hunter chose to withdraw from the role of Pike[33] when creator Gene Roddenberry was asked to produce a second pilot episode ("Where No Man Has Gone Before") of which an edited version of the same name aired in 1966.[34][35]

"The Cage" never aired during Star Trek's original run on NBC. It was presented by Roddenberry as a black-and-white workprint at various science fiction conventions over the years after Star Trek's cancellation but was not released on home video until 1986 when Paramount Home Video produced a "restored" release of "The Cage" (a combination of the original black-and-white footage and color portions of the Season 1 episode "The Menagerie") complete with an introduction by Gene Roddenberry.[36]

On October 4, 1988, Paramount Pictures aired a two-hour television special, hosted by Patrick Stewart, called "The Star Trek Saga: From One Generation To The Next", which featured, for the first time, a full-color television presentation of "The Cage". In some markets, the special did not air until October 15, 1988.[36] In the United States, "The Cage" was first released to DVD in December 2001.[37] It was later included on the final disc in both the original and "remastered" Season 3 DVD box sets (listed with the original air date of October 15, 1988).[5][8][38]

The also planned-as-pilot "Where No Man Has Gone Before" in its original form (production number 02a) had been forwarded to NBC, but only a re-worked, re-edited, re-formatted, cut version was later aired under the same name, not as a pilot but as the third episode of the series (production number 02b). Afterwards, over the years the original "alternate" version was thought to be lost but later appeared as bootleg VHS tapes at conventions, until a print of it was discovered in 2009 and subsequently released on home video under the title "Where No Fan Has Gone Before" - The Restored, Unaired Alternate Pilot Episode as part of the TOS season 3 box set on Blu-ray;[29] it has not been released on DVD yet. This version remains unaired.

Season 1 (1966–67)[edit]Edit

Main article: Star Trek: The Original Series (season 1)

After Roddenberry's second pilot episode, "Where No Man Has Gone Before", received a more favorable response from NBC,[34][35] Star Trek finally aired its first episode - "The Man Trap" - at 8:30PM on September 8, 1966.[40] "Where No Man...", which eventually aired in a re-edited format as the series' third episode, retained only Spock as a character from "The Cage" but introduced William Shatner as Captain KirkJames Doohan as chief engineer Scotty, and George Takei as physicist (later helmsman) SuluDeForest Kelley and Nichelle Nichols joined the cast as ship's surgeon Dr. McCoy and communications officer Uhura in "The Man Trap", the first aired episode of the series.

Although her character of Number One was not retained from "The Cage", Majel Barrett returned to the show as a new character, nurse Christine Chapel, and made her first of many recurring appearances in "The Naked Time". Grace Lee Whitney appeared in eight episodes as yeoman Janice Rand, beginning with "The Man Trap". Whitney left the series after "The Conscience of the King",[34][41][42] but would later make minor appearances in the firstthirdfourth, and sixth Trek films as well as one episode of the sequel series Star Trek: Voyager.

Star Trek's first season comprised 29 episodes, including the two-part episode "The Menagerie", which includes much of the footage from the original pilot, "The Cage". Other notable episodes include "Balance of Terror", which introduces the Romulans; "Space Seed", which introduces Khan Noonien Singh and serves as the basis for Star Trek II: The Wrath of Khan and Star Trek Into Darkness; "Errand of Mercy", in which theKlingons make their first appearance; and the critically acclaimed,[43] Hugo-Award-winning episode [44] "The City on the Edge of Forever", which features Kirk, Spock, and McCoy traveling into the past through theGuardian of Forever.

Season 3 (1968–69)[edit]Edit

Main article: Star Trek: The Original Series (season 3)

After Star Trek's second season, NBC was prepared to cancel the show due to low ratings.[45][46] Led by fans Bjo and John TrimbleTrek viewers inundated NBC with letters protesting the show's demise and pleading the network to renew the series for another year.[46][47] After NBC agreed to produce a third season, the network promised Gene Roddenberry that the show would air in a favorable timeslot (Mondays at 7:30 PM),[45][46] but later changed the schedule so that Trek would air in the so-called "death slot" — Friday nights at 10:00PM.[45][48] In addition to the "mismanaged"[46] schedule, the show's budget was "seriously slashed"[45] and Nichelle Nichols described the series' eventual cancellation as "a self-fulfilling prophecy".[49]

Star Trek's final, 24-episode season began in September 1968 with "Spock's Brain".[2] The third season also includes "The Tholian Web", where Kirk becomes trapped between universes; this episode would later be revisited by two 2005 episodes of the prequel series Star Trek: Enterprise. The last episode of the series, "Turnabout Intruder", aired on June 3, 1969,[2] but Star Trek would eventually return to television in animated form when the animated Star Trek debuted in September 1973.

UK Transmission[edit]Edit

Star Trek was first broadcast in the UK on BBC One starting on July 12, 1969 with the episode "Where No Man Has Gone Before". The first episode broadcast in color was "Arena" on November 15, 1969. The running order was very different from the US original with the episodes being shown in four seasons between 1969 and 1971. "The Cage" was first transmitted on August 19, 1992 and three episodes, "Plato's Stepchildren", "The Empath" and "Whom Gods Destroy" were not broadcast in the UK until early 1994.[51]

The BBC broadcast versions of the episodes that differed from the way they had been shown in America. The opening elements of each episode were transposed so that the title sequence was the first thing seen, followed by the teaser, and then into the rest of the episode without a pause. These prints were used up until the 1990s when fresh prints were obtained and the episodes were broadcast as originally made for the first time.
