The organization became particularly known for its live performances, called camp shows, through which the entertainment industry helps boost the morale of servicemen and women. From the start, Hollywood was eager to show its patriotism, and many celebrities joined the ranks of USO entertainers. They went as volunteers to entertain, and celebrities continue to provide volunteer entertainment, in military bases in the U.S. and overseas, sometimes placing their own lives in danger, by traveling or performing under hazardous conditions. In 2011, the USO was awarded the National Medal of Arts.
