With World War I an entire system of ideas how wars work collapsed. Suddenly it was no longer mostly soldiers who had to fight. War became an engagement of every day's life. Everybody got involved.
Propaganda therefore changed as well. The campaigns were no longer temporarily and recent but had to be planned for years. Who failed in organizing it or used the wrong keywords failed. Masters of modern propaganda became the British, whereas the Germans failed completely in the beginning.

The German philosopher Walter Benjamin (1892-1940) and author believed in the duty to educate people (including children) politically. In the German radio he had a series where he tried to do this. These texts are most important for Radio work - even today. Still he is more famous for his critiques on literature and art. Benjamin immigrated to Paris in 1934 and killed himself in 1940 at the boarder between Spain and France as he was afraid to get caught by German troops.
