The New York Times has published an introduction to podcasting authors and audiobook podcasts.

The article focuses on author Scott Sigler, who helped pioneer audiobook podcasting with his sci-fi thriller, Earthcore. Sigler introduced an Earthcore podcast in 2005, describing it at the time as the first podcast-only novel.

After being snubbed by publishers for years, Mr. Sigler began recording his first book, EarthCore, in 2005. He offered it as a podcast in 22 episodes (roughly 45 minutes each) that he posted online and sent free to subscribers for downloading. Before long, Mr. Sigler had 5,000 listeners; by the time he finished releasing his second novel, “Ancestor,” last January, he had 30,000, as he does for “The Rookie,” which is playing now.

With initial printings of novelists’ first books running as low as 2,000 copies, Mr. Sigler has a substantial audience, enough finally to attract a small Canadian publisher, Dragon Moon Press, which published “EarthCore” in 2005 and will release “Ancestor” on April 1.

Mr. Sigler also recently signed with a New York agent, Byrd Leavell of the Waxman Agency, who expects to park his latest, “Infection,” with a major publisher.

Others have turned to the Internet to build their audience, including Cory Doctorow, who offered the text of “Down and Out in the Magic Kingdom” as a free download in 2003. But Mr. Sigler is among the vanguard of authors stapling their literary aspirations to the iPod.

“A lot of no-name authors like me are getting massive grass-roots exposure, and some of us are going to percolate to the top and get on the best-seller list,” Mr. Sigler said.

According to Sigler, the Earthcore features “killer robots, dismemberments, decapitations, machine guns, actual science, blood, blood & more blood, and a super-hot villainess who dabbles in S&M.” Sigler has since introduced several more novels via podcasting.
