Awareness of and Receptivity to the Fresh Empire Tobacco Public Education Campaign Among Hip Hop Youth.

Among the campaign audience of Hip Hop-identified youth, awareness of the Fresh Empire campaign was higher in treatment than control markets at individual survey rounds, and increases in campaign awareness were greater in treatment than control markets over time. Campaign advertisements also elicited positive audience reactions. Findings suggest that heavily digital campaigns may take longer to achieve Centers for Disease Control and Prevention-recommended 75% quarterly awareness.
