Halloween Horror Nights wasn't always a $575M-per-park juggernaut.

In this Spooky Commerce special, we trace how October became the secret weapon for combating theme park slumps, why Spirit Halloween's pop-up model prints money in dead malls, and what happens when horror becomes the ultimate immersive commerce experience.
