The fact that each season of American Horror Story has a new theme, characters, and a rotating cast, may have seemed like a risky move at the start, but it's sure paying off. The first episode of American Horror Story: Coven broke a series record. Here are the details provided by FX:

via Red Carpet Crash: "The premiere episode of FX’s critically-acclaimed miniseries American Horror Story: Coven (10/9/13, 10:00-11:12 PM) was the most-watched telecast ever of the American Horror Story franchise, recording 5.54 million Total Viewers, 3.87 million Adults 18-49 (3.0 rating) and 2.34 million Adults 18-34 (3.5 rating), which ranked #1 for the night in Adults 18-34 against all broadcast competition in primetime (8:00-11:00PM), and it ranked #2 in Adults 18-49 behind Modern Family. (Cable program rankers for Wednesday will be available later this afternoon.)

On a Live+Same Day basis, last night’s debut episode of Coven, “Bitchcraft,” posted all-time AHS franchise highs across the board for the American Horror Story franchise and marked gains of +44% in Total Viewers (5.54 million vs. 3.85 million) and +39% in Adults 18-49 (3.87 million vs. 2.78 million) compared with the debut of American Horror Story: Asylum, and an astounding +74% in Total Viewers (5.54 million vs. 3.18 million) and +90% in Adults 18-49 (3.87 million vs. 2.04 million) compared with the premiere of American Horror Story: Murder House. Coven also scored franchise highs in Women 18-49 (2.36 million) and Women 18-34 (1.47 million).

The premiere telecast and encore runs (11:12 PM and 1:25 AM) of Coven combined to deliver 7.78 million Total Viewers and 5.36 Million Adults 18-49."
