Digital technology for iPod does for radio what blogs did for the Internet.
Each afternoon, stay-at-home dad Dan Klass waits until his young daughter falls asleep and then dashes into a home-office that doubles as a broadcast studio.
Hunched over a microphone, the former stand-up comedian uses the quiet time to record his very own amateur talk show titled "The Bitterest Pill." After an introductory tune that sounds like a mash-up between a mariachi band and the funk bass of the "Seinfeld" theme, the Los Angeles native launches into a breathless, free-form soliloquy that encompasses subjects such as child-rearing, politics, and an embarrassing encounter with Meg Ryan at a party. It ends when his daughter stirs in the next room.
Mr. Klass's month-old program is hardly a conventional radio show. For starters, it isn't broadcast on any of the nation's airwaves. Instead, Klass transmits his show in a format called "podcasting," a new Internet-based medium that has the potential to revolutionize the content of traditional radio as well as reshape our listening habits.
The idea behind a podcast is simple, yet brilliant. Instead of using portable MP3 players such as the iPod only for listening to music, new software called iPodder allows one to download prerecorded radio shows onto the devices.
Though several radio stations have begun podcasting shows, the medium's most visible impact has been empowering DJs like Klass to broadcast their own homemade radio shows with just a microphone, a computer, and a dash of brio.
"Aspiring writers and journalists have their blogs, aspiring movie directors have their Apple iMovies, and aspiring DJs/radio producers now have podcasting," says Reinier Evers, the founder of trendwatching.com, in an e-mail interview. "Podcasting allows for tens of thousands of new 'radio' stations - or, more likely, tens of thousands of radio programs."
