The March of Time was a newsreel that was shown in movie theaters from 1935 - 1951. It was prepared by Time, Inc. as the idea of executive Roy Edward Larsen. It was launched in over 500 theaters and was an immediate success with audiences, but because of its high production costs (estimated at $50,000 per episode, which were released about one per month), was a money loser. It was ultimately ended when the widespread adoption of television and daily news shows obliviated the newsreel format.
The newsreel included both reporting, on-location shots, and dramatic reenactments.
It was satirized in Orson Welles' Citizen Kane as News on the March.
From 1931 to 1935, The March of Time was presented as a radio show.*1
