Star Trek, Behind The Scenes

After Roddenberry
Roddenberry died on October 24, 1991 leaving Executive Producer Rick Berman in control of the franchise. TNG had the highest ratings of any of the Star Trek series and was the #1 syndicated show during the last few years of its original seven-season run.
In response to TNG's success, Paramount began production of a spin-off series Deep Space Nine, which was released in 1993. While never as popular as TNG, DS9 had solid ratings, and it also lasted seven seasons.
In January 1995, a few months after TNG ended, a fourth TV series, Voyager was released. Star Trek saturation reached a peak in the mid-1990s with DS9 and Voyager airing concurrently and three of the four TNG-based feature films being released in 1994, 1996 and 1998. Voyager was the flagship show of the new United Paramount Network (UPN) and thus, the first Star Trek series since the original that was shown on a major network. The show also ran for seven seasons until 2001, making it the longest running show in UPN's short history.
