In response to allegations of blacks that broadcasting stations, especially in the South, discriminate against their interests, the Office of Communications of the United Church of Christ undertook a two-year project (1968-70) to combat discriminatory practices. The project attacked two widespread practices: non-employment or under-employment of blacks, and failures of stations to give blacks access to the air to provide programs which satisfy their needs and tastes. Community action, through monitoring of stations by citizen groups and threats of legal action in license renewal requests before the FCC, influenced the programming and employment practices of stations to an extent that amounted to significant social change. Cases in Texarkana, Arkansas; Shreveport, Louisiana; Atlanta, Georgia; and Charlotte, North Carolina, are discussed. The Office of Communication expects much greater citizen participation in broadcasting in the immediate future. Of particular concern are the charges that educational stations (again, especially in the south) also fail to give attention to minority programming and employment needs. (JK)
