programs that were preempted from earlier in the week due to special programming, in the 8:00–10:00 p.m. (Eastern and Pacific Time) time period. This primetime scheduling allowed for many of the network's affiliates to air local newscasts during the 10:00–11:00 p.m. (Eastern and Pacific Time) time period. Most of UPN's programming through the years was produced by Paramount Television or a Viacom-owned sister company (Viacom Productions, Big Ticket Television, Spelling Television or CBS Productions). UPN's first official program was Star Trek: Voyager, with the first comedy shows to debut being two short-lived series: the Richard Jeni starring vehicle Platypus Man and Pig Sty. Other notable UPN programs during the network's existence included The Sentinel, Moesha, Star Trek: Enterprise, WWE SmackDown, America's Next Top Model, Girlfriends, the Moesha spin-off The Parkers, Veronica Mars, Everybody Hates Chris, and the animated adaptation of Dilbert. In Summer 2005, UPN aired R U the Girl, in which R&B group TLC (not with Left Eye) searched for a woman to join them on a new song. The network also produced some special programs, including 2001's Iron Chef USA. Much of UPN's comedy programming between 1996 and 2006 (particularly those that aired as part of the network's Monday evening lineup) was largely aimed at African American audiences, with minor exceptions in shows such as Clueless, Realitycheck and Head Over Heels. UPN occasionally acquired series canceled by the other broadcast networks, including former WB series Buffy the Vampire Slayer and Roswell (both of which moved to UPN in 2001, Buffy was picked up after The WB chose not to renew it due to issues with license fees while Roswell joined UPN after that same network also canceled the series), and former ABC series Clueless and The Hughleys. The first program that UPN acquired from another network was In the House, which moved to the network from NBC (which canceled the LL Cool J sitcom after its second season) in 1996. In its later years, as part of the network's desire to maintain its own identity with its own unique shows, UPN instituted a policy of "not picking up other networks' scraps", which was a strong argument when fan pressure was generated in 2004 for them to pick up Angel, the spin-off of Buffy the Vampire Slayer which had been dropped from The WB. UPN aired only one regular sports event program: the much-hyped XFL in 2001, airing Sunday
