foreign to the American ethic, and they exposed and attacked them accordingly. … A cinematic agent provocateur, the March of Time turned over a lot of rocks, both at home and abroad, and illuminated the creatures it found beneath them. The demagogues and quacks whom they attacked in the 1930s may seem like obvious targets now, but they didn't seem so then. They were popular, powerful, frightening people, and the March of Time stood entirely alone in theatrical motion picture circles as a muckraker. In late 1936, producer Roy E. Larsen reluctantly left The March of Time to serve as publisher of Life, a weekly news magazine that began publication in November 1936. Time executives had long vacillated over launching such a magazine, but the success of The March of Time's experiments in pictorial journalism overcame the hesitation of the corporation's board of directors. Larsen proposed that the new magazine be named The March of Time, but the name Life was purchased from the owners of a declining periodical. Life magazine was a great success and notable influence on photojournalism throughout its 36-year history. Louis de Rochemont succeeded Larsen as producer of The March of Time, while Larsen continued to supervise the operations of the series on behalf of the Time corporation. Examining the subjects of The March of Time, series historian Raymond Fielding found that episodes dealing with a single country and its affairs comprised 32.6 to 36 percent of the entire series. Economic issues were the subject of 10 percent of the episodes, and domestic politics 5 percent. Between 1935 and 1942, approximately 24 percent of the episodes were about war or the threat of war; from December 1941 until the end of World War II nearly every episode dealt with war. "Although the March of Time was professedly nonpartisan, a clear and persistent antifascist tone was becoming apparent in its analysis of world politics and rising militarism", Fielding wrote. "'Rehearsal for War' [August 6, 1937] was unquestionably anti-Franco, which was exactly what liberal staff members had intended." During Louis de Rochemont's tenure (1935–1943), 14 percent of the March of Time episodes were about the impact of specific individuals on political, economic and military events — a number that dropped significantly after his departure. De Rochemont's particular interest in the geopolitical role of the world's waterways resulted in 7.5 percent of all episodes devoted to the subject.The March
