Media Systems Dependency Theory
Media systems dependency theory (MSDT), or simply "media dependency," was developed by Sandra Ball-Rokeach and Melvin DeFleur in 1976. The theory ties together the interrelations of broad social systems, mass media, and the individual into a comprehensive explanation of media effects. At its core, the basic dependency hypothesis states that the more a person depends on media to meet needs, the more important media will be in a person's life, and therefore the more effects media will have on a person.

“The media no longer ask those who know something ... to share that knowledge with the public. Instead they ask those who know nothing to represent the ignorance of the public and, in so doing, to legitimate it.”
—Serge Daney (1944–1992)
“Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
—Ralph Waldo Emerson (1803–1882)
“For in all the world there are no people so piteous and forlorn as those who are forced to eat the bitter bread of dependency in their old age, and find how steep are the stairs of another man’s house. Wherever they go they know themselves unwelcome. Wherever they are, they feel themselves a burden. There is no humiliation of the spirit they are not forced to endure. Their hearts are scarred all over with the stabs from cruel and callous speeches.”
—Dorothy Dix (1861–1951)
“There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.”
—A.J. (Alfred Jules)
