FX‘s American Horror Story: Asylum got off to a strong start last night with 3.85 million total viewers. Ryan Murphy and Brad Falchuk’s horror anthology series was once again particularly strong in the younger demos, posting 2.78 million adults 18-49 (2.20 rating) and 1.78 million adults 18-34 (2.63 rating). Among 18-34, it was the top program at 10 PM last night on broadcast or cable, while in 18-49, it finished second behind only CBS’ CSI (2.39 rating).

American Horror Story: Asylum outpaced any single telecast of its predecessor, American Horror Story, and was up sharply from AHS‘ series debut last fall: +37% in adults 18-49; +50% in adults 18-34 and +21% in total viewers. With FX’s Sons Of Anarchy already a big demo force in the Tuesday 10 PM slot, winning the hour the last couple of weeks with a 2.3-2.4 rating in 18-49, FX now has a tight grip on both Tuesday and Wednesday’s 10 PM slots in the key 18-49 demographic.

FX’s lead-in movie to Asylum, the broadcast premiere of Twilight: New Moon, was also strong, delivering 1.55 million adults 18-49.
