Founded in 1967 under the Public Broadcasting Act, CPB was created as a nonpartisan nonprofit to channel federal appropriations to public television and radio stations across the United States, including affiliates of PBS and NPR.

The Corporation for Public Broadcasting announced Friday that it will begin shutting down, weeks after Congress canceled previously approved funding for the nation's steward of public media access.

Arizona PBS said it has been searching for ways to fill the multimillion-dollar funding gap left by the federal cuts.
