A propaganda film is a film that involves some form of propaganda. Propaganda films spread and promote certain ideas that are usually religious, political, or cultural in nature. A propaganda film is made with the intent that the viewer will adopt the position promoted by the propagator and eventually take action towards making those ideas widely accepted. Propaganda films are popular mediums of propaganda due to their ability to easily reach a large audience in a short amount of time. They are also able to come in a variety of film types such as documentary, non-fiction, and newsreel, making it even easier to provide subjective content that may be deliberately misleading.Propaganda is the ability "to produce and spread fertile messages that, once sown, will germinate in large human cultures". However, in the 20th century, a "new" propaganda emerged, which revolved around political organizations and their need to communicate messages that would "sway relevant groups of people in order to accommodate their agendas". First developed by the Lumiere brothers in 1896, film provided a unique means of accessing large audiences at once. Film was the first universal mass medium in that it could simultaneously influence viewers as individuals and members of a crowd, which led to it quickly becoming a tool for governments and non-state organizations to project a desired ideological message. As Nancy Snow stated in her book, Information War: American Propaganda, Free Speech and Opinion Control Since 9-11, propaganda "begins where critical thinking ends." Source: Wikipedia (en)
