"During the 1930s Europe was convulsed by political violence. The National Socialists rose to power in Germany and Fascists campaigned in Britain, Spain and France. Yet Europe was also transformed in this decade through new applications of film, photography and radio. In fact, these political and technological developments were closely intertwined. The Image of the Popular Front demonstrates this by tracing the history of the Popular Front in France, one of the first mass movements to take advantage of the new forms of mass media." http://www.loc.gov/catdir/enhancements/fy0708/2006044835-d.html.
