The WB has made official what many have suspected: "Sabrina, the Teenage Witch" is ending its seven-season run (four on ABC, three on The WB). The one-hour series finale is scheduled for Thursday (April 24), the first night of sweeps.

The writing has been on the wall for some time. The show revamped its premise at the start of the season to reflect Sabrina's (27-year-old Melissa Joan Hart) life as a college graduate with a job at a magazine, yet couldn't change its title because of legal issues with the publisher of the comic books on which the show is based.

The finale will find Sabrina preparing for her wedding to Aaron Jacobs (Dylan Neal, "Dawson's Creek"). She'll take a bachelorette-party cruise to Bermuda with friends Morgan (Elisa Donovan) and Roxie (Soleil Moon Frye), but they find their powers don't work in the Bermuda Triangle and have to use their human skills to get out.
