When students walk across the Yard with earbuds in, they could be listening to music or talking on the phone. But nowadays, there’s a good chance they’re listening to a podcast.

What listeners may not know is that podcasts started right here at Harvard in 2003.

Daniel Jones is a digital media producer at the Berkman Center for Internet & Society at Harvard University, and works with the center’s podcast, Radio Berkman. He spoke about two previous fellows at the center, Christopher Lydon and Dave Winer, and how they essentially created the first podcast.

“What they did together was figure out: ‘Hey, we can tweak the code of RSS to recognize audio,’” Jones said. “With that seemingly simple act, they made audio subscribe-able.”

Podcasts are particularly popular now, especially since the success of the “Serial” podcast series last year, Jones noted. While many people were listening and subscribing to podcasts before that, “Serial” proved you could have a blockbuster — with subscribers tuning in with the same intensity with which they’d listen to a Taylor Swift album, he added.

“Audio is more intimate than almost any other medium … it’s being whispered in your ear,” Jones said. “In fact, it asks a lot of you. Your brain has to build the entire set of the story, and picture what the characters look like, so you never really just zone out.”

Podcasts are so popular, in fact, that the Berkman Center will host a HUBweek event called “State of the Podcast” on Oct. 6. Panelists will include Lydon, a radio host at WBUR, Jake Shapiro, the founder of Public Radio Exchange (PRX), and some local podcasters.

“It will be an amazing conversation about the past, present, and future of podcasting … and how cool that we’re doing it at Harvard — the birthplace of the podcast,” Jones said.

The podcast scene remains strong at Harvard. With more than 50 audio collections hosted on the University’s SoundCloud and iTunes U channels, there is something for everyone.
