What are the distinctions between national & local underwriting guidelines?

PBS National Underwriting Guidelines apply to underwriting credits that are attached to content distributed by PBS – local stations can set their own policy for local underwriting and credits. Accordingly, some stations have stricter guidelines than PBS, while others are more liberal. Many stations choose to model their local underwriting guidelines after the PBS national guidelines because they apply FCC rules and policy and serve to promote continuity between national and local underwriting messages.  It is also worth noting that other national distributors of content—including American Public Television (APT) and the National Educational Telecommunications Association (NETA) for example --  have their own set of national underwriting guidelines, which may differ slightly from PBS guidelines. The same is true of various regional or multi-market sales operations including the Major Market Group (MMG), Texas PBS and The Association of Public Media in Florida (FPBS), among others.
