UPN

UPN, or the United Paramount Network, was a US television network owned by Viacom. It was the original broadcast network for Star Trek: Voyager and Star Trek: Enterprise.

UPN launched on with the two-hour series premiere of Voyager,. They broadcast a small number of other original shows, but the initial programming lineup was mostly syndicated shows drawn from the vast body of programs available to Paramount Pictures. Voyager was the only original program from the network's launch to last into its second season. When Voyager ended its television run in, Enterprise replaced it.

The idea of a Paramount Pictures television network was not new to the 1990s; in the late 1970s there were plans for a Paramount Television Service to compete as a 4th network alongside CBS, NBC and ABC. Star Trek: Phase II was intended to be one of the lead shows of the new network. The plans fell apart as Phase II became. Eventually the market niche of "4th network" would be filled by FOX in the 1980s. Paramount was also a partner in the failed DuMont Television Network of the late 1940s and early 1950s.

In, the network officially changed its name to just the initials "UPN". In the early 2000s the network began to change its focus by targeting an African-American audience and produced urban-themed situation comedies with African-American casts, as well as professional wrestling and reality shows. This change in targeted demographics and programming is considered to be highly influential in the cancellation of Enterprise after only four seasons of a projected seven season run.

Jason Bonet visited the set of Star Trek: Enterprise on to let the cast sign pictures. He worked for the section "affiliate relations" regarding Star Trek.

UPN, then owned by the CBS Corporation, the former Viacom, ceased to exist on when it combined with Time Warner's "The WB" network to become a new network called "The CW". With no Trek series in production since, Star Trek is not a part of this new network's schedule.
