Monitoring the exposure of "America Responds to AIDS" PSA campaign.

The "America Responds to AIDS" campaign is the focal point of an integrated mass communications system for AIDS education and information dissemination developed by the National AIDS Information and Education Program of the Centers for Disease Control. Television and radio public service announcements are an integral part of the campaign. One measure of their success is the extent to which they are aired on both national and local levels. Since 1987, the total dollar value for air time donated to the "America Responds to AIDS" campaign is more than $65 million, representing 47 percent of all donations of air time for AIDS public service announcements. These results suggest that the campaign has been successful in reaching a large proportion of the public.
