Propagandists encouraged the public to contribute more to war production and victory gardens, convinced people to save some of their materials so that more materials could be used for the war effort, and promoted the sale of war bonds using a wide range of media.

The war strengthened the position of the advertising sector in American society, rebuking prior criticism.
