　　Public-service advertising is generally sponsored by a nonprofit institution, civic group, religious organization, trade association, or political group. Typically, it is directed at some humanitarian cause, philosophical ideal, political concept, or religious viewpoint. Most public-service advertising involves the donation of time or space on part of the medium in which it is featured, although free time or space is not a prerequisite for this type of advertising. Groups such as the Red Cross,United Way, and International Ladies Garment Workers Union have sponsored a great deal of public-service advertising. Advertisements which relate to public issues predate the commercial advertising sector. During the Civil War, the government sold bonds via free newspaper ads which were so effective that they resulted in the first national paid ad campaigns for baking powder, soap and railroad travel. The PSA in its current form was in many ways shaped by the Ad Council (initially called the War Advertising Council) during and after World War II.
　　As an advanced social cultural environment, the public service advertising has a great influence on young people such as moral knowledge, ethics and the development of the character.
