Power of Fanfiction
Fanfiction reshapes the power dynamics between authors and consumers. Now, consumers can create their own sequels, prequels, or alternative stories without even consulting the author. There are many websites that publish any fic (a story made by fans) that the user wants.
Publishing fics is not a new hobby of fans. For example, the bestseller Fifty Shades of Grey by E.L. James has been initially created as a fic in the universe of Twilight that has thousands of other fics. As a result, young adult girls seem to have gone crazy about this book.
Of course, there is no denying that some fanfics are written pretty well and will be interesting to the members of one or another fandom. Note: fandom is a circle of people who are avid fans of something. Almost every fictional creation nowadays has its own fandom where the imagination of people creates often bizarre but sometimes great stories.
To some extent, the reboots of classic movies can also be considered as fanfiction with the only exception that they are worth millions of dollars.
