Mark Twain
I had no idea that this genre of storytelling was started by Mark Twain with his novel A Connecticut Yankee in King Arthur’s Court, I’ve seen so many takes on this story with the protagonist time traveling to an ancient society and taking with him/her modern technologies and ideas never knowing where it got it’s start, until I wiki'ed this movie (I wikipedia almost everything)
I find the novel to be significant and everything that followed including this movie to be insignificant.
