Tweeny Twilight Fans were sent into a bloodthirsty frenzy when Robert Pattinson and Kristen Stewart took their vampire romance to the big screen. While high school girls all over fantasized about Bella and Edwards twisted love, a darker more mature audience discovered True Blood, HBO’s answer to America’s current corpse crush. Though the True Blood novels were written significantly earlier than Mormon Meyer’s Twilight, the internet has been buzzing wildly about both for months—each getting hundreds of social media mentions per hour. The two have very different sub-plots, but when taking a quick glance at these two different series, it’s hard to ignore their initial similarities.

Twilight: Bella, a mortal girl falls in love with a mind-reading vampire (also known as bloodsucker). She struggles to become accustomed to the dangers of their world and the physical and emotional implications that their relationship brings. Her best friend is a werewolf. Lots of sexual tension and teen angst.

True Blood: Sookie, a mind-reading mortal girl, falls in lust with a vampire (making her a “fang-banger”). She struggles to become accustomed to the dangers of their world and the social, physical, and emotional implications that their relationship brings. Her boss is a shape-shifting dog. Lots of seXXX.

We checked out some OneRiot search data to see if we could shed any light on America’s thriving coffin craze, hoping to find out which set of vampires were most popular.

If you check out the graph below, you’ll see that Twilight has always kept a bit of an edge on True Blood, consistently gathering a few more social media mentions in places like Twitter. However, their rise and declines on the graph practically mirror each other, showing that whenever the web’s interest for vampires goes up, it goes up everywhere - which is interesting. Of course, that all changes as True Blood skyrockets off the chart leaving Twilight in the dust (which can easily be explained by the debut of their Season Two premiere which brought in 3.7 million viewers, 157% up from season one’s debut).

With these two blood-sucking powerhouses dominating Hollywood, we’re left only to speculate as to why America is again obsessed with the mysteries of vampire sex - apparently the recipe of lust, violence, fangs, and a pinch of humor is a good one.
