The Public Radio Exchange (PRX) is a nonprofit web-based platform for digital distribution, review, and licensing of radio programs. PRX is the largest on-demand catalog of public radio programs available for broadcast and Internet use.

According to PRX's site, the mission of PRX "is to build a fair market for creative audio content and an online community of increasing gains; to create more opportunities for diverse programming of exceptional quality, interest, and importance to reach more listeners."

PRX uses streaming and downloadable digital audio as an audition and delivery tool for terrestrial radio stations which in turn broadcast to their listeners over the air or online. As a result, station and independent work is offered the opportunity for multiple broadcasts, existing radio pieces with lasting value remain accessible through the PRX database, and natural affinity groups of stations are able to support content exchanges around local and regional issues. PRX is the "long tail" for public radio - an expanding on-demand archive that generates new opportunities for good work to find good homes.

PRX delivers these core services via a database-driven web application through which stations and producers upload, store, search, audition, rate, review, and download audio pieces, as well as manage and monitor transactions, rights, usage statistics, and payments within their individual and group accounts. PRX technology has a powerful capacity to catalogue, display, search, and organize large bodies of programming resources.

The PRX site and services launched in September 2003 after a two-year planning, research, and development phase supported by the Corporation for Public Broadcasting, the National Endowment for the Arts, and the Ford Foundation. Since then PRX has received additional support from the NTIA Technology Opportunities Program, the MacArthur Foundation, the Open Society Institute, and the Surdna Foundation.
