In Europe, the triangle CD logo continues to be widely used. The old U.S. civil defense logo was used in the FEMA logo until 2006 and is hinted at in the United States Civil Air Patrol logo. Created in 1939 by Charles Coiner of the N. W. Ayer Advertising Agency, it was used throughout World War II and the Cold War era. In 2006, the National Emergency Management Association—a U.S. organization made up of state emergency managers—"officially" retired the Civil Defense triangle logo, replacing it with a stylised EM (standing for Emergency management). The name and logo, however, continue to be used by Hawaii State Civil Defense and Guam Homeland Security/Office of Civil Defense.
