The Fangoria Horror Business Model

Along with Stephen King and Hammer Horror, Fangoria magazine was one of the earliest influences on my obsession with Horror in all its various forms. I scored a binder filled with the first 12 issues when I was 14 and became a devout subscriber. 40+ years later, Fangoria’s transformation from a struggling print magazine into a multimedia powerhouse is a story of resilience, innovation, and strategic growth. Their journey provides valuable insights for anyone in the horror business – whether you’re running a small indie publishing house, starting a podcast, or looking to scale your horror-themed merchandise line.

The broken light that comes & goes between the darkness either side of dawn speaking of your memory ushering in each day one, as if a step away from you the next, a step toward...
