The Public Broadcasting Service (“PBS”) is committed to serving the public interest by providing content of the highest quality that enriches the marketplace of ideas, unencumbered by commercial imperative. Throughout PBS’s history, four fundamental principles have guided that commitment. Editorial integrity: PBS content should embrace the highest commitment to excellence, professionalism, intellectual honesty and transparency. In its news and information content, accuracy should be the cornerstone. Quality: PBS content should be distinguished by professionalism, thoroughness, and a commitment to experimentation and innovation.
