What has changed in the world of reading and what does the future hold?
Some major changes I have seen in the way we read books
1) E-readers and audiobooks have come into focus, opening doors for people with disabilities to enjoy more books. The popularity of e-books could drive paper book prices up if it hasn't already. This article from NPR discusses how with e-books, publishers can use a temporary price drop to create the experience of discovery, which use to be a phenomenon unique to brick and mortar bookstores.
2) We shop online for everything, books included. I think brick and mortar bookstore will really suffer, especially large chains. Our Barnes and Noble is already stuffing itself full of toys and curiosities to get people in the door. It never seems to be without a crowd, but I do wonder what will happen in the next five or so years. I don't see a lot of small bookstores anymore, but Half-Price Books seems to be still kicking, and bookstores that offer a unique experience, such as Kids Ink are still able to keep their doors open.
3) Crazy futuristic stuff will happen. Things we are doing with technology right now seemed impossible 20 years ago. 20 years from now, whoa... we will probably be reading from software directly implanted into our brains or something. Maybe a projection directly on our wrists? I feel like I've seen something along those lines already. Ah yes, here it is.
Other than that, I have no idea. I feel like the draw for human beings to the written/typed/spoken word, to telling and hearing stories, to sharing information is so universal and timeless that any changes that come along will not effect the deep down integrity of our human connection to reading.
