"Practice" Makes Perfect: ABC Drama Picked Up For Full Season

Looks like sometimes spin-offs do work, after all.

Private Practice, from Grey's Anatomy creator Shonda Rhimes, has scored a full-season order from ABC, garnering a full 22 episodes this season. (That it, unless that writers' strike actually does materialize after all.)

Drama revolves around Dr. Addison Montgomery, who left Seattle Grace for the sunnier climes of Santa Monica and finds herself working at a medical cooperative clinic run by her now divorced medical school friends.

Series, which airs in the ultra-competitive Wednesday nights at 9 pm timeslot, is the highest rated new series this season. Over the course of its first four airing, Private Practice has managed to hold onto rough 12.8 million viewers.

Also getting full season orders today: CBS' freshman comedy The Big Bang Theory and returning series The Unit, which had previously only received a 13-episode order this season.
