Do we even want a next big thing? Sometimes I mull over the differences between mediums, and Movies are very much on the look out for the Next Big Thing. But television with the rise of cable programming has become more diverse. Certainly there are hits and mega hits (I was floored when a friend and I were interrupted during a conversation about Game of Thrones by someone who had never heard of Game of Thrones). But, for example (and I admit I don't flip through channels much these days) Are there a bunch of Walking Dead wanna be shows out there? TV seems to be truly diverse in a way movies will never be, and books could be, possibly...
I like speculating about the Next Big Thing as much as the next person, but what if we go along without a Twilight or Hunger Games or even a Divergent for a few years. Will it hurt anything?
I believe Harry Potter did huge things for YA as a 'bookstore category', but...I'm not sure Twilight and even HG did the same. I'm afraid that their popularity narrowed the market in unfortunate ways. Twilight made publishers hungry for books that would appeal to 9 year olds through 90 year olds, pushing plenty of good contemporary and certainly books that were edgy YA and NOT appropriate for grandmothers to buy, read and then give to their elementary aged grandchildren, to the sidelines.
So what do we see right now. Contemporary with good hook= possibility of making waves. Different types of fantasy selling, some selling very well. Horror finally making a come-back, and hopefully back in circulation for awhile (forever?). A few historicals. Dystopian and Paranormal, particularly paranormal romance = only selling if they are touting as next 'big things' or from established authors. A few science fiction titles.
I think diversifying, can only be good for the readers, who do not all like the same things, and good for authors because there is more room for creativity, rather than clones of the Juggernauts.
With that being said, I'll keep watching for the next big thing, with the same level of curiosity as anyone else.
