The committee used newsprint, posters, radio, telegraph, and movies to broadcast its message. It recruited about 75,000 "Four Minute Men," volunteers who spoke about the war at social events for an ideal length of four minutes. They covered the draft, rationing, war bond drives, victory gardens and why America was fighting. They were advised to keep their message positive, always use their own words and avoid "hymns of hate." For ten days in May 1917, the Four Minute Men were expected to promote "Universal Service by Selective Draft" in advance of national draft registration on June 5, 1917.
