Clark Boyd was technology correspondent for The World, the daily international news programme co-produced by the BBC and WGBH and funded by Public Radio International. By February 2008 he had been podcasting for three years, and this post carried an interview recorded with him in Boston looking back over that run and ahead at the future of radio.

The question in the title was the one the conversation was built around, and in 2008 it was still open: whether a podcast is radio delivered by another route or a form with conventions of its own. Boyd was answering it from three years of doing both inside a public radio newsroom, at a point when the podcast was still an experiment attached to a broadcast programme.
