The Four Minute Men were a group of volunteers authorized by United States President Woodrow Wilson, to give four-minute speeches on topics given to them by The Committee on Public Information. In 1917-1918, around 7,555,190 speeches were given in 5,200 communities. The topics dealt with the American war effort in the First World War and were presented during the four minutes between reels changing in movie theaters across the country. Also, the speeches were made to be four minutes so that they could be given at town meetings, restaurants, and other places that had an audience. This is an instance of "viral marketing" before its time.
In 1917, the war in Europe had been raging for three years and America's involvement had not begun. Woodrow Wilson had just been re-elected president under the slogan "He Kept Us Out of War". The British had been calling for the United States involvement and eventually helped convince Wilson, with the help of events such as the Zimmermann Telegram and the sinking of the RMS Lusitania. Eventually on April, 6th 1917 the US Congress declared war on Germany.
With a large number of German Americans in the United States, and many others with strong isolationist feelings, there was a strong need for a propaganda campaign to stir support for the war. This effort had many unique challenges to meet to address the existing political climate. Wilson needed to speak directly to the fragmented and spread out audience in the United States. He had to address the country's self-perception to generate support for the war. The Four-Minute Men provided an answer to these challenges.
In addition, the Four Minute Men urged citizens to purchase Liberty Bonds and Thrift Stamps.
The Four Minute Men idea became a useful tool in the propaganda campaign because it addressed a specific rhetorical situation. One of the challenges of the effort was the fragmented audience of the United States. Many different heritages were represented in the United States, and the president needed their support for the war. To address each groups specific needs, the director of the Four Minute Men, William McCormick Blair, delegated the duty of speaking to local men. Well known and respected community figures often volunteered for the Four Minute Men program. This gave the speeches a local voice. Also, the four minute men were given general topics and talking points to follow and rotated between theaters to help the speeches seem fresh, instead of generic propaganda speeches.
