(FORTUNE Magazine) – In the '80s ponytailed heartthrob Adam Curry broke ground as one of MTV's first veejays. Two decades later Curry, 40, has popped up at the intersection of blogs and radio.

In 2004 he and partner Dave Winer (the man many credit with inventing blogs) launched a site called iPodder.org, which allows listeners to automatically download podcasts--essentially bloggers' webcasts--to MP3 players. About 2,500 podcasts are listed on the site, from sports shows to indie bands. Curry even hosts one about the podcasting world that has 50,000 subscribers.

Later this winter Curry and partners plan to launch a podcasting network, offering an edited selection of the web's best dispatches and tools for neophytes to create their own casts. Just as blogs have challenged mainstream media, Curry predicts that podcasts will take on radio and satellite. "With podcasting, people can tune out the world and listen to whatever they choose," says Curry. "In a way we're really looking at the dismantling of the monoculture," he says. Guess it's a good thing he's not at MTV anymore. -- Nadira A. Hira
