The Public Telecommunications Act of 1988 requires the Corporation for Public Broadcasting to report annually on the provision of service to minority and diverse audiences by public broadcasting and public telecommunications entities. This report includes the third triennial assessment and the seventh annual report on services. The assessment is based on the results of a national survey which sampled members of the three largest minority communities specified in the Act--African-Americans, Asian-Americans and Hispanics--along with Whites, and provides statistically comparable results so that the attitudes and perceptions of all groups can be examined together. As in all previous reports on services, this one provides quantifiable, objective measures of public broadcasting's commitment to serve diverse audiences, including production and broadcast of television and radio programming; community outreach activities; audiences' use of programming; minority employment, hiring and training within public broadcasting; efforts to increase the participation of minorities in public broadcasting; and efforts to increase the number of minority public television and radio stations meeting the objective criteria that enable them to qualify for financial support from the Corporation. Some statistical data from the survey is also included. (AEF)
