via press note:
Last night's SUPERNATURAL was the series' most watched episode (2.7M) in more than three years (10/15/10).
Week to week, SUPERNATURAL was up 22% in total viewers and up 10% in both W18-34 (1.1/3) and in A18-49 (1.1/3), and flat in A18-34 (0.9/3).
SUPERNATURAL outrated original episodes of ABC's comedies in the 9pm hour in A18-34, and W18-34, and outrated Trophy Wife in the 9:30-10pm half hour in A18-49.
At 8pm, an all-new episode of THE ORIGINALS rose 14% week to week in total viewers (2.35M) and rose 11% in A18-49 (1.0/3).
One note that there were some preemptions for NCAA basketball in 2.4% of the country last night, so these numbers could be adjusted slightly in the nationals.
