Media manipulation is a series of related techniques in which partisans create an image or argument that favours their particular interests. Such tactics may include the use of logical fallacies and propaganda techniques, and often involve the suppression of information or points of view by crowding them out, by inducing other people or groups of people to stop listening to certain arguments, or by simply diverting attention elsewhere. In Propaganda: The Formation of Men's Attitudes, Jacques Ellul writes that public opinion can only express itself through channels which are provided by the mass media of communication – without which there could be no propaganda. It is used within public relations, propaganda, marketing, etc. While the objective for each context is quite different, the broad techniques are often similar.
As illustrated below, many of the more modern mass media manipulation methods are types of distraction, on the assumption that the public has a limited attention span.
Activism is the practice or doctrine that has an emphasis on direct vigorous action especially supporting or opposing one side of a controversial matter. It is quite simply starting a movement to effect or change social views. It is frequently started by influential individuals but is done collectively through social movements with large masses. These social movements can be done through public rallies, strikes, street marches and even rants on social media.
A large social movement that has changed public opinion through time would be the 'Civil Rights March on Washington', where Martin Luther King Jr. performed his 'I Have a Dream' speech attempting to change social views on African Americans in the United States of Americ, 28 August 1963. Most of King's movements were done through non-violence rallies and public speeches to show the white American population that they were peaceful but also wanted change in their community. In 1964, the 'Civil Rights Acts' commenced giving African Americans equality with all races.
