Which American TV series follows a trio of sisters, the most powerful good witches of all time?

I loved charmed

I loved charmed, not so much the revamped series, with the 3 m's but the original one with the 3 p's Piper Phoebe and Prue, and of course Paige when she took over from Prue. I mean you can't have a night club called M 3 can you?! I think that they should have left it well alone. and left us with our memories of a great series.
