A page on the Freepress.net site; quote below is from this page: "While media technology has advanced in the 42 years since public broadcasting was created, the need has only grown for noncommercial, not-for-profit media, available free to the public with a mission to inform, educate, inspire and engage. Public media means more than just PBS and NPR. It includes all media outlets and formats whose mission is to serve the public, not to earn a profit. This noncommercial sector aims to educate, engage and inform audiences, and it offers an alternative to the mainstream, commercial media."

Website for Native Public Media. From their mission statement: "Native Public Media Strengthening and Expanding the Voice of Native America The struggle of Native America has long been the struggle for freedom.  Fundamentally, the freedoms that are so important to all Americans are the same freedoms that are important to Native people:  to be able to make our voices heard and make our own decisions about issues affecting our lives, our health, our safety, our governments, and our homes.  The effort to secure these freedoms, however, has time and again been undercut by a centuries-long legacy of economic and cultural exploitation and the resulting socio-economic conditions that have long kept Native people poor and powerless.
