The audience put it ahead of NBC’s freshman drama "Revolution," which drew 8.61 million viewers. ABC’s "Castle" won the hour with 10.94 million viewers.

But "Revolution" drew the highest rating among the key target audience, adults 18-49, by garnering 3.3 percent of the total viewing audience and 9 percent of those watching TV at the time, CBS said. "Five-0" drew 2.1 percent of the total viewing audience and 5 percent of those watching TV.
