The Big Bang Theory: 15 Insane Details You Definitely Missed
2. The Comic Book Store Predominantly Features DC Comics And Merchandise
When they're not at Caltech, in their apartments, or at the Cheesecake Factory, then chances are the gang are hanging out at the comic book store. Frequented as often as their apartments, the store allows Leonard, Sheldon, Howard, Raj, and at times their partners the chance to browse the latest comic books, t-shirts, memorabilia, etc.
Take a closer look, though, and you'll notice that the store features roughly 99% DC Comics-related merchandise. Very rarely will you see or hear mentioned a Marvel product in the store, despite the gang's infatuation with both comic book brands.
It's not an oversight from the prop department; it's a logical bit of product placement from Warner Bros, the overarching media family that encompasses The Big Bang Theory. DC is owned by Warner Bros, too, thus making it easier to include an abundance of DC products in the show.
Very rarely has the store featured products from other franchises, though it has happened, such as in season five's "The Russian Rocket Reaction", where Leonard and Sheldon purchase a LongClaw sword from Game of Thrones.
