Star Trek: Voyager is an American science fiction television series created by Rick Berman, Michael Piller, and Jeri Taylor. It originally aired between January 16, 1995 and May 23, 2001 on UPN, lasting for 172 episodes over seven seasons. The fifth series in the Star Trek franchise, it served as the fourth sequel to Star Trek: The Original Series. Set in the 24th century, when Earth is part of a United Federation of Planets, it follows the adventures of the Starfleet vessel USS Voyager, as it attempts to return home after being stranded in the Delta Quadrant on the far side of the Milky Way galaxy.
Paramount Pictures commissioned the series following the termination of Star Trek: The Next Generation to accompany their ongoing Star Trek: Deep Space Nine. They wanted it to help launch their new network, UPN. Berman, Piller, and Taylor devised the series to chronologically overlap with Deep Space Nine and to continue themes—namely the complex relationship between Starfleet and ex-Federation colonists known as the Maquis—which had been introduced in The Next Generation and Deep Space Nine. Voyager was the first Star Trek series to include CGI technology for space scenes and the first to feature a female captain, Kathryn Janeway (Kate Mulgrew), as the lead character. Berman served as head executive producer in charge of the overall production, assisted by a series of executive producers: Piller, Taylor, Brannon Braga, and Kenneth Biller.
Being set in a different part of the galaxy to preceding Star Trek shows, Voyager gave the series' writers space to introduce new alien species as recurring characters, namely the Kazon, Vidiians, Hirogen, and Species 8472. During the later seasons, the Borg—a species created for The Next Generation—were introduced as the main antagonists. During Voyager's run, various episode novelisations and tie-in video games were produced; after the show ended, various novels continued the crew's adventures.
