Changes

Propaganda reflects shifting technologies, media, and ideas that leaders have attempted to portray in different periods and states. Propaganda has often including the bending of truth or even invention, but the target of propaganda has also shifted. Technological shifts have often resulted in shifts in the style of how propaganda is portrayed. Initially, propaganda was often limited in its appearappearance and audience, as the medium of art or writing was only understood by a relatively small number of people. With the printing press, this shifted to a more mass audience, resulting in a transformation in how propaganda was portrayed. By the 20th century, propaganda spread globally through radio and even television such as through films. The World Wars and Cold War greatly accelerated the use of new media and sometimes not only state institutions but also private institutions , such as the film industry, into supporting a wider message that became global.
