Spotify

The Interactive Advertising Bureau recently estimated that podcast industry revenue grew by 53 percent last year and is projected to reach $1 billion by 2021.

With so much year-over-year growth, it shouldn’t be any surprise that many media companies  are aggressively expanding their podcast operations. This is certainly true for Vox Media, which over the past few years has launched over 150 podcasts on topics that include technology, politics, and sports. The audio medium is now an eight-figure business for Vox.

I recently sat down with Marty Moe, the head of Vox Media Studios, to talk about how the company is monetizing these podcasts, what he thinks about Spotify’s entry into podcasting, and why he thinks he can grow Vox’s podcast revenue from eight to nine figures.
