Surprisingly, not too much. There was the Harry Styles fanfic that got published and has a movie deal, but otherwise, scratching the serial numbers off of fanfics and publishing them is going somewhat out of style (at least it hopefully is).Man, with how much this shit plagues the YA literature, I just cannot imagine what romance is like nowadays. I haven't touched a romance novel in years simply because I find many of them to be too hokey, and/or are just cut from the same cloth in how they choose the setting, the main heroine (if you wish to call her that), the main tall, dark and handsome stud, the antagonistic slimy fiancé who's secretly misogynistic and puts down the heroine any chance he gets, and their badly-written sex position of choice for their first time on top of the flowery purple prose they're consistently formatted in. They're all the same fucking books that bored housewives keep salivating over in their rocking chairs while their rugrats are at school and their husbands slave away at the office. And yes, this includes YA books no thanks to Twilight and the stupid "paranormal romance" genre it kickstarted.
But I imagine the romance novels are also dictated by your Cassandra Clares and other fanfic writers who dance around copyright to get their shitty yaoi fic published officially, so bleh. Glad I stopped reading them so I can focus on polishing up my own work of what I want, even though it sounds just as stupid for writers to circlejerk to their own works. I'm also baffled by how it is my grandmother can put up with reading YA novels just because she clutches her pearls over adult books yet once dipped her toes in the literary world with the same themes she's complained about (my dad likes to snark about it much to her displeasure, and she always has the same excuse, "Because I was telling a story!"). Wonder what she would think if I were to just, I dunno, casually drop this video into her inbox while bitching about the state of the industry.
I will say that there has been some drama in the romance community. This woman named Faleena Hopkins decided to copyright the word 'cocky' for romance titles. She actually went after some authors who used it and threatened to sue them for everything they had if they didn't change the title of their books. She wasn't even the first one to use it, and the whole issue was that people were using the same generic stock photos as her for their erotic romance novels too and people bought those instead of hers. She did eventually let go of the copyright, but not until after some people had to lose a lot of money and time redoing their covers just before launch and thus losing a lot of money on all the merchandise and the copies they'd already had printed that had to be pulled. Apparently the woman isn't even a very good writer anyway, certainly not enough that this move could be justified. She came out and discussed it after it was all over, but came across as so pretentious and bitchy. Google #cockygate for more info (seriously, that was what it was called).
That was the worst of it I think, but when you've got a genre that is predominately women authors, I'm just waiting to see what else is going to happen.
