What is the main purpose of the Corporation for Public Broadcasting?

The main purpose of the Corporation for Public Broadcasting (CPB) is to support non-commercial programming, which includes funding public television and radio stations in the United States. Established by Congress in 1967, the CPB's mission is to ensure that all Americans have access to high-quality content that is educational, informative, and culturally enriching. This is achieved by providing grant funding to public broadcasting entities, allowing them to create diverse and community-focused programming that might not be feasible in a commercial environment.

The other options do not align with the CPB's core mission. For example, regulating commercial broadcasting falls under the auspices of the Federal Communications Commission (FCC), while CPB does not produce independent films or distribute theatrical releases; its focus is strictly on supporting public media.
