I’ve seen statistics and articles that claim the audiobook industry is thriving, or growing every year, and in part it may be due to companies like RandomHouse. They’re partnering with the state of Florida to promote audio book listening while driving (the only place to listen, if you ask me).
Random House has a very attractive site up with special offers such as free shipping and a contest to win a fantasy road trip. It’s well done, and I hope they roll it out to other states. Part of the difficulty of working in this industry is the small niche size, so more listeners will convince more publishers to produce more books.
