The United Service Organizations Inc. (USO Show) is a nonprofit organization that provides programs, services and live entertainment to United States service members and their families.
The USO was founded in 1941 in response to a request from President Franklin D. Roosevelt to provide morale and recreation services to uniformed military personnel. This request led six civilian agencies -- the Salvation Army, YMCA, YWCA, NCCS, NTAA and the NJWB -- to unite in support of the troops.
