Amazon announced a new publishing platform on Wednesday called Kindle Worlds, which will give both established authors and aspiring fan fiction writers the chance to earn royalties based on their work. Fan fiction is a rather murky topic, given that it often combines beloved characters and franchises in rather unusual scenarios. Regardless, the medium has proven to be incredibly popular on the Internet and it’s clear that Amazon sees an opportunity to earn some additional profits. The company has secured licenses from Warner Bros. Television Group’s Alloy Entertainment division for Gossip Girl, by Cecily von Ziegesar; Pretty Little Liars, by Sara Shepard; and Vampire Diaries, by L.J. Smith. All three are also incredibly successful TV shows in their own right, which should add to the interest both from fans and aspiring writers.
