Why are pop culture zombies so strongly associated with communication & communications technologies?
There are several apparently-independent books/movies where cell phones turn people into zombies (and, as far as I am aware, none where cell phones turn people into vampires or werewolves).
There’s stuff like Pontypool (book & film) or Hyenas (book), where zombieism is either spread by language or created by the absence of language.
More conventional zombie media is absolutely obsessed with communication too. We’re constantly seeing broadcast media, or pirate radio…
