Star Trek: Voyager premiered in January 1995 as the flagship for the nascent United Paramount Network. The network didn't survive, but the show completed seven lively seasons and 172 episodes, joining the ranks of other classic Star Trek series of the era. The show trapped its crew in the Delta Quadrant: decades from the nearest Starfleet outpost, they were left to find a way home. It was intended to return to The Original Series' loose idea of a starship left to its own devices deep in unexplored space.
