In May 2005, Christopher Lydon and his longtime producer Mary McGrath partnered with University of Massachusetts Lowell’s radio station WUML, WGBH (FM), and Public Radio International to produce Open Source as a daily call-in radio program.

The show was syndicated by 32 NPR stations, before it was canceled on October 16, 2006. In 2007, Lydon moved to Brown University’s Watson Institute for International Studies to podcast hourlong conversations under the name Open Source. In 2013, Lydon and McGrath returned to WBUR to produce Open Source as a weekly show.

Open Source airs twice a week on WBUR, Thursday at 9pm and Sunday at 2pm. The Open Source podcast reaches listeners in over 150 countries each week. Open Source also produces ongoing series on its website, including “Reading Chekhov,” a reading of Anton Chekhov’s short stories by Boston actors and academics, and “Parachute Radio,” international conversations from Ghana, India, Pakistan, Egypt, Jamaica, Singapore and Cuba. Open Source is the world’s oldest active podcast.
