It attracted 1 million more viewers than the previous episode, and 2.4 million more than the show's average before the writer's strike. The episode achieved a 4.5/12 rating in the key 18–49 demographic among adults, and was the fourth highest-rated show of the evening; it subsequently achieved the show's highest rating ever in the 18–49 demographic. Show co-creator Bays later said that Britney Spears' appearance greatly benefited ratings: "And by golly she put our show on the map. It can't be overstated. Britney Spears rescued us from ever being on the bubble again. Thanks Britney!"
