Which pop culture property, do academics study the most? The answer from Slate, 

Buffy the Vampire Slayer by a mile. More than twice as many papers, essays, and books have been devoted to the vampire drama than any of our other choices—so many that we stopped counting when we hit 200. Buffy even has its own journal: Slayage, a publication of the Whedon Studies Association (named for the show’s creator, Joss Whedon), which features titles like “Real Vampires Don’t Wear Shorts: The Aesthetics of Fashion in Buffy the Vampire Slayer” and “Killing us Softly? A Feminist Search for the ‘Real’ Buffy.”
