During the war, while the U.S. government used various media to publicize the war effort, many volunteer groups and civic activities emerged to boost morale on the front lines, the most famous of which was the United Service Organizations (USO), founded in February 1941. The United Service Organizations (USO) was founded in February 1941 to provide performances, entertainment and psychological help to soldiers. According to incomplete statistics, the United Service Organizations organized a total of 293,738 performances throughout World War II, and more than 161 million people attended their performances. Of course, the performances were not always smooth, and 28 of them were die on duty on tour due to plane crashes or contagious diseases.


In addition to these frontline sympathy activities, in January 1941, United Service Organizations joined with the American Library Association and the American Red Cross to launch the National Defense Book Campaign. The National Defense Book Campaign was launched in January 1941 to encourage the American public to donate books and magazines to the troops as daily reading material for soldiers.





The Americans also began gradually promoting Victory Mail in June 1942 as a regular means for soldiers to bond with their loved ones and boost their morale in combat. Of course, the American public could also send Victory Mail to soldiers on the front lines, but they were also required not to ask about anything related to the war on the front lines




“The U.S. government adopted Kodak’s Victory Mail as a communication tool to keep in touch with soldiers and officers on the front lines.” This was a Kodak commercial created at the time to promote the Victory Mail. The books and letter exchanges donated by the United Service Organizations for the front did serve to stabilize the soldiers on the front lines.
