UPN and Paramount Network Television jointly announced Wednesday that this will be the last season of “Star Trek: Enterprise.” The fifth live-action “Star Trek” series will have its series finale on Friday, May 13.

A prequel to the original “Star Trek” series, “Enterprise” premiered on UPN on Sept. 26, 2001, and aired for its first three seasons on Wednesdays at 8 p.m. (ET). On Oct. 8, 2004, “Enterprise” moved into its current slot on Fridays at 8 p.m. Through its four-year run, “Enterprise” produced a total of 98 episodes and earned four Emmy Awards.

In January, Paramount Domestic Television sold “Enterprise” into off-network syndication in more than 90 percent of the country, including 49 of the top 50 markets. The show will have weekly over-the-air runs starting in fall 2005.

Speculation had been building concerning “Enterprise’s” demise, especially after UPN embarked on a strategy of building a younger female audience. UPN President of Entertainment Dawn Ostroff declined to comment on the series’ future at the Television Critics Association Winter Press Tour in January.
