I ... presumed SHIELD was a thing, already, in the comic books. Which would make it like a decade or two old at least by now. Wasn't SHIELD a thing in the comic books? Or did they just not have an acronym for it yet? They just liked saying it in big bold letters. I swear that's where Nick Fury's always been from, even before he was a black man.. Not that any of it really matters, but with so many nerds in here, I'm surprised nobody has mentioned this. Either that or I'm delusional. And I'm not a comic buff of any sort
