Advertising Campaign By Nadav Kander

In the United States, the granting of television and radio licenses by the FCC is contingent upon the station broadcasting a certain amount of public service advertising. To meet these requirements, many broadcast stations in America air the bulk of their required public service announcements during the late night or early morning when the smallest percentage of viewers are watching, leaving more day and prime time commercial slots available for high-paying advertisers.
Public service advertising reached its height during World Wars I and II under the direction of more than one government. During WWII President Roosevelt commissioned the creation of The War Advertising Council (now known as the Ad Council) which is the nation's largest developer of PSA campaigns on behalf of government agencies and non-profit organizations, including the longest-running PSA campaign, Smokey Bear.
