The United Service Organizations, popularly known as the USO, was incorporated in New York on February 4, 1941, to provide recreational opportunities and resources for members of the U.S. Armed Forces on leave.

At the recommendation of President Franklin Roosevelt, the task was put in the hands of existing public service organizations. The USO was organized by representatives of six social service organizations as a private, nonprofit organization. The organizers included the Jewish Welfare Board, the National Catholic Community Service, the Salvation Army, the Travelers Aid Association of America, the Young Men’s Christian Association (YMCA), and the Young Women’s Christian Association (YWCA). Over the course of World War II, the USO boasted more than 1 million civilian volunteers and operated more than 3,000 recreational clubs. Set up quickly in churches, museums, barns, railroad cars, storefronts, and other locales, USO clubs were places for both lively social activity and quiet contemplation. Some soldiers came to dance and watch movies, others to pursue traveler’s information or assistance, still others to write letters, lounge, eat, or seek religious counsel.

Soon after the founding of the USO, the organization created a subsidiary, Camp Shows Inc., to produce professional-quality shows with volunteers from the entertainment world. Traveling shows, which included dramatic and musical performances, vaudeville-style revues and beyond, featured well-known performers such as Bob Hope, Joe E. Brown, Lena Horn and Joan Blondell, as well as many other actors and production staff members from stage and screen.

The USO was disbanded in 1947, then reorganized during the Korean War and expanded considerably during the Vietnam War. It continues to provide a variety of services to members of the armed forces and their families.
