In 2016, a "New York Times" study of the 50 TV shows with the most Facebook Likes found that "as with several other shows that focus on the supernatural", "The Vampire Diaries" was "slightly more popular outside of cities. That said, the show's fandom has the smallest amount of spatial variation of all 50 shows".
