Author Scott Sigler first made news when he decided to release his book EarthCore as a weekly podcast last year. Sigler produced the audio book himself and released it a few chapters at a time via podcast and garnered 10,000 subscribers. The innovative author has now achieved a “second first” by putting the audio novel on the iTunes Music Store. The entire 20 episode audio book can be purchased from iTunes for $9.99 and it will be interesting to see how well this sells. It could pave the way for other authors to self-publish in audio format.
