Ratings: ‘American Horror Story’ Finale Hits Season High, Wins Top Cable Slot

Ryan Murphy/Brad Falchuck supernatural drama draws in 3.22 million viewers for season swan song

The season finale of "American Horror Story" really killed it in more ways than one.

Wednesday's Season One swan song drew 3.22 million total viewers — a high for the series, which premiered Oct. 5. It was also cable's top-rated program among the advertiser-coveted adults 18-49 demographic, drawing 2.19 viewers in that demo.

While impressive, the performance doesn't mark a dramatic improvement over "AHS"'s maiden episode. The series' maiden episode drew 3.2 million total viewers, with 2 million in the demo.

Overall, the season has averaged 4.4 million total viewers when Live+7 data is factored in. When video-on-demand and online views are added, the Ryan Murphy/Brad Falchuk series is averaging 8.6 million total viewers, going by data from the first five weeks.

"American Horror Story" has yielded the highest-rated first season in FX history, besting "Justified" by 29 percent in total viewers and Murphy and Falchuk's earlier FX offering, "Nip/Tuck," by 50 percent in the adults 18-49 demo.
