The show ran eight season between 1998 and 2006. It regularly outperformed Buffy The Vampire Slayer, which aired on the same network (and itself was revived as a comic book). Charmed starred Alyssa Milano, Shannen Doherty, and Holly Marie Combs as sister witches.
Zenoscope Entertainment (the guys who bring us Grimm Fairy Tales) published a 24 issue ninth season a few years ago, and are now following it up with a tenth.
The first issue of the new run will make its debut at New York Comic Con on October 9th.
