In the 1930s a new type of illustrated press appeared, based on photojournalism. Dominated by the success of the US magazine Life, this model gradually spread throughout the Western world where it replaced the illustrated news magazines that had made their appearance in the 1840s. But this transition was more complex than it is generally believed to have been. Photojournalism magazines were published in France and Germany from the late 1920s. Their international development was however impeded by WWII, which probably contributed to delaying the birth in 1949 of Paris Match, the French version of Life.
