Last week’s fourth season premiere earned the title of the most-watched telecast in FX history, The Hollywood Reporter  has learned.

Following its record-breaking premiere stats for the highly anticipated premiere of Freak Show, the anthology series from Ryan Murphy and Brad Falchuk has been picked up for a fifth season.

Casting has not yet been announced for the next season, but fans are wondering if Jessica Lange’s previous announcement of retiring AHS following this season remains set.

“The American Horror Story anthology has had the highest growth trajectory of any show in FX history, not to mention an unprecedented track record of success in awards recognition,” said FX CEO John Landgraf. “With Ryan Murphy and his partners, Brad Falchuk, Dante Di Loreto and Tim Minear at the helm, the show’s success is not surprising. AHS continues to deliver amazing stories, a brilliant troupe of actors led by Jessica Lange, and a visual style unlike any other on TV. With Nip/Tuck, Glee, The Normal Heart, and American Horror Story, Ryan Murphy has established himself as one of the most successful and prolific producers of this generation. We expect AHS: Freak Show and the next incarnation of AHS to further his legacy.”

Season five of American Horror Story will return in October 0f 2015 with a 13-episode run.
