Manufacturers had to produce war materiel instead of consumer products during World War II. However, they continued advertising. In this ad, General Electric promises better consumer goods after the war and explains how hard GE is working to win the war.
Propaganda efforts also included integrating information about how to support the war into radio programming. In this document from the Office of War Information, propaganda themes were rotated among programs. Advertisers and their agencies could choose how to integrate that theme into the program: as an announcement, a plot point, or even a song.
