Dependen

Dependency Theory
media depends on the social context
(or: Media System Dependency Theory)
History and Orientation
Dependency theory was originally proposed by Sandra Ball-Rokeach and Melvin DeFleur (1976). This theory merged out of the communication discipline.
Dependency theory integrates several perspectives: first, it combines perspectives from psychology with ingredients from social categories theory. Second, it integrates systems perspectives with elements from more causal approaches. Third, it combines elements of uses and gratifications research with those of media effects traditions, although its primary focus is less on effects per se than on rationales for why media effects typically are limited. Finally, a contextualist philosophy is incorporated into the theory, which also features traditional concerns with the content of media messages and their effects on audiences. Research generated by this model had tends to be more descriptive than explanatory or predictive.
 
Core Assumptions and Statements
Dependency theory proposes an integral relationship among audiences, media and the larger social system. This theory predicts that you depend on media information to meet certain needs and achieve certain goals, like uses-and-gratifications theory. But you do not depend on all media equally. Two factors influence the degree of media dependence. First, you will become more dependent on media that meet a number of your needs than on media that provide just a few. The second source of dependency is social stability. When social change and conflict are high, established institutions, beliefs, and practices are challenged, forcing you to reevaluate and make new choices. At such times your reliance on the media for information will increase. At other, more stable times your dependency on media may go way down.
