Charmed is an American fantasy drama television series created by Constance M. Burge and produced by Aaron Spelling and his production company Spelling Television, with Brad Kern serving as showrunner. The series was originally broadcast by The WB from October 7, 1998, until May 21, 2006. The series narrative follows a trio of sisters, known as The Charmed Ones, the most powerful good witches of all time, who use their combined "Power of Three" to protect innocent lives from evil beings such as demons and warlocks. Each sister possesses unique magical powers that grow and evolve, while they attempt to maintain normal lives in modern-day San Francisco. Keeping their supernatural identities separate and secret from their ordinary lives often becomes a challenge for them, with the exposure of magic having far-reaching consequences on their various relationships and resulting in a number of police and FBI investigations throughout the series. The series initially focuses on the three Halliwell sisters, Prue, Piper, and Phoebe. Following Prue's death in the third-season finale, their long-lost half sister Paige Matthews assumes her place within the "Power of Three" from season four onwards.
