Star Trek: Voyager is an American science fiction television series created by Rick Berman, Michael Piller, and Jeri Taylor. It originally aired from January 16, 1995, to May 23, 2001, on UPN, lasting for 172 episodes over seven seasons. It is the fifth series in the Star Trek franchise. 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 to the Alpha Quadrant 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 the ongoing Star Trek: Deep Space Nine. They wanted it to help launch UPN, their newly established network. Berman, Piller, and Taylor devised the series to chronologically overlap with Deep Space Nine and to maintain thematic continuity with elements that had been introduced in The Next Generation and Deep Space Nine. The complex relationship between Starfleet and ex-Federation colonists known as the Maquis was one such element and a persistent central theme. Voyager was the first Star Trek series to feature a female commanding officer, 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. Set in a different part of the galaxy from 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 Voyagers run, various episode novelizations and tie-in video games were produced; after it ended, various novels continued the series' narrative. Production Development As Star Trek: The Next Generation ended, Paramount Pictures wanted to continue to have a second Star Trek TV series to accompany Star Trek: Deep Space Nine. The studio also planned to start a new television network, and wanted the new series to help it succeed. This was reminiscent of Paramount's earlier plans to launch its own network by showcasing Star Trek: Phase II in 1977. Initial work on Star Trek: Voyager began in 1993, when the seventh and final season of Star Trek: The Next Generation and the
