in the text. Use details from the text to support your answer.

The influence of the media on society has for a long time preoccupied researchers in the field of communication. Various normative, social scientific, and critical communication theories have addressed how media influence social change. Early media effects theories assumed a direct and unmitigated influence of media on individuals and society. Later research questioned the assumption of all-powerful media effects, launching what became known as the limited-effects tradition. From those early days of communication research, there has been a constant ebb and flow of theories and empirical research attempting to understand the real effect of media on social change.

Numerous theories have also attempted to understand the effect of the media on social change from a variety of perspectives and for different objectives. These include theories of media and democratization, theories of development communication and social learning, and theories in health communication, social marketing, and participatory communication. Also, a variety of areas of inquiry in mass communication dealt with social change. These include research on alternative and pirate media, public service and educational broadcasting, public opinion and political communication, and research on propaganda.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
