American Horror Story is an American anthology horror television series that premiered on FX in 2011, with each season telling a self-contained story set in a different haunted location. Its opening title sequence, with its stark typography and disturbing imagery, quickly became one of the most recognisable parts of the show. As clips spread on video platforms and social media, the theme became shorthand for horror itself, detached from any single season. Creators still reach for it because it instantly signals dread, even to viewers who have never watched an episode.
