Here's a nice description from the Universal Newsreel channel:
In the pre-TV era, people saw the news every week in their neighborhood movie theaters. Newsreels were shown before every feature film and in dedicated newsreel theaters located in large cities. Universal Newsreel, produced from 1929 to 1967, was released twice a week. Each issue contained six or seven short stories, usually one to two minutes in length, covering world events, politics, sports, fashion, and whatever else might entertain the movie audience. These newsreels offer a fascinating and unique view of an era when motion pictures defined our culture and were a primary source of visual news reporting.
Here's video from 1933, of FDR and one of his fireside chats, in which he outlines his economic recovery plan.
