Well many authors are going with self-publishing services (like 'Kindle Direct Publishing'). They're the indies of the book industry it seems. They don't have to rely on publishers because these self-publishing services make it easier to get your work out there, and you can set your own price. So maybe we will see more 99 cent books this way.
And videogames cost quite a bit to make as well, since you have to pay the coders, artists, designers, voice actors, etc.
