PRX

What PRX does

PRX (Public Radio Exchange) is a 501(c)(3) nonprofit public media organization founded in 2003 and headquartered across Boston and Minneapolis. It operates a two-sided audio marketplace and technology platform serving three constituencies: independent audio producers and podcast publishers seeking distribution and monetization infrastructure, 935+ public radio stations across all 50 U.S. states seeking programming content, and listeners of public radio and podcasts. Its core products are PRX Exchange, an open online marketplace where producers upload and license audio stories and series for broadcast on member stations, and PRX Dovetail, an IAB Podcast Measurement 2.1 Certified podcast publishing platform providing content management, real-time analytics, sharable embeddable players, and dynamic audio ad insertion validated at scale by Serial (100M+ downloads) and S-Town.

PRX generates revenue through five principal streams: listener and donor contributions (501(c)(3) IRS #263347402), corporate sponsorship and underwriting of its content portfolio (including Reveal, The Moth, Snap Judgment, The World, and Latino USA), recurring Dovetail platform service fees from 260+ podcast publishers (Radiotopia, Night Vale Presents, Gen-Z Media, GBH, TED Audio Collective), recurring broadcast distribution fees from 935+ station affiliates, and foundation grants from the Corporation for Public Broadcasting, MacArthur Foundation, Knight Foundation, Templeton Foundation, Surdna Foundation, and Alfred P. Sloan Foundation. The 2018 merger with Public Radio International (PRI) substantially expanded its content portfolio and station footprint, adding flagship programs such as The World and Latino USA. Complementary units include PRX Productions (bespoke audio production for commercial partners including Patagonia and Ben & Jerry's), PRX Remix (a 24/7 curated streaming channel available via SiriusXM, smart speakers, and TuneIn), the Radiotopia podcast network (founded 2014 in partnership with Roman Mars of 99% Invisible), and the PRX Podcast Garage community training facilities in Boston and San Francisco. Leadership is led by CEO Kerri Hoffman with a board drawing from major public media organizations (GBH, Oregon Public Broadcasting, KQED, WHYY) and industry leaders including Google and PBS NewsHour.
