The following is written by Jake Shapiro, CEO of Public Radio Exchange. It is cross-posted from PBS MediaShift. We announced PRX's partnership with the Knight Foundation to create the Public Media Accelerator about a month ago. Since then, it's become clear that the accelerator concept is new to many people in the non-profit and public media worlds, even as tech folks fret that accelerators have jumped the shark. Our tagline for the Public Media Accelerator is "seeking mission-driven entrepreneurs changing media for good." We're in a time of remarkable technology innovation, and our goal is to channel the forces driving that growth towards public service media. The two forces, the tech sector and public media, need each other: The tech sector will gain from public media's high-quality content, commitment to community, and public service mission; and public media will gain from technology's network efficiencies, professional and social connections, and radical new distribution paths.
