Buffy the Vampire Slayer
The series premiered on March 10, 1997, on The WB and concluded on May 20, 2003, on UPN. The series narrative follows Buffy Summers (played by Sarah Michelle Gellar), the latest in a line of young women known as "Vampire Slayers", or simply "Slayers". In the story, Slayers or the 'Chosen Ones' are "called" (chosen by fate) to battle against vampires, demons, and other forces of darkness. Being a young woman, Buffy wants to live a normal life, but as the series progresses, she learns to embrace her destiny. Like previous Slayers, Buffy is aided by a Watcher, who guides, teaches, and trains her. Unlike her predecessors, Buffy surrounds herself with a circle of loyal friends who become known as the "Scooby Gang".
UPN
In 2001, UPN entered into a public bidding war to acquire two series from The WB, "Buffy the Vampire Slayer" and "Roswell", from producing studio 20th Century Fox Television. UPN eventually outbid The WB for the shows and aired them together on Tuesday nights until "Roswell" ended its run in 2002, "Buffy" ended its run the following year. New shows began to breathe life into the network starting in the fall of 2003 with "America's Next Top Model" and sitcom "All of Us" (which was produced by Will and Jada Pinkett Smith), followed up by the fall 2004 premiere of the mystery series "Veronica Mars" and the fall 2005 premiere of the Chris Rock-produced and narrated sitcom "Everybody Hates Chris".
