Folks at ABC are happy with the premiere of the new series "Cavemen," which scored strong numbers on Tuesday. "On its debut telecast, ABC’s Cavemen opened at the #1 position at 8pm in Adults 18-49 (tie), Adults 18-34 and key men (M18-34/M18-49). The show held second in the slot among viewers (9.0m), trailing only CBS’ time period veteran NCIS. Cavemen overshadowed its season premiere competition in the half-hour, NBC’s Singing Bee, by 2.4 million viewers and by 43% in Adults 18-49. Across each of the key men demos (M18-34/M18-49/M25-54), Cavemen generated ABC’s top ratings in the time period since last November," the network said.
