ABC struck gold with the highly anticipated crossover of the twin medical dramas Grey's Anatomy and Private Practice with top ratings last Thursday. Both Private and Grey's averages were up from the week before, and the two handily beat out the competition, with Practice surprisingly having an easier time doing so.
Grey's 5.8/14 rating trumped perennial ratings winner CSI's 4.9/12 and a strong showing from The Office with 4.6/11. On the other hand, Private Practice's competition was nowhere in site, with Eleventh Hour and ER languishing in the bottom of the ratings with 2.7/7 and 2.6/7 ratings respectively.
Private Practice is a spin-off of Grey's Anatomy.
