It definitely helps that the Walking Dead universe isn’t just tethered to AMC’s live-action series, and it can only aid in building the show’s audience that the horror brand survives in so many other areas of entertainment, from its comic book source material to the stellar Telltale video game series to toys to tie-in novels and much more.
All of that basically means if The Walking Dead somehow lost all of its viewers that didn’t fit into the 18-49 demographic, it would still be one of the most impressive successes on TV.
And since it’s mostly demo-slotted adults who are buying all of those products, they’re the most likely to tune in on Sunday nights, and the cycle can continue ad nauseam.
