ABSTRACT
Shannon and Weaver produced the first formal transmission model of information. In the 1950s Wilbur Schramm transformed Shannon and Weaver's model into a general model of the human communication process, both direct interpersonal communication and those forms of communication mediated by communication technology. According to Schramm's model, all forms of human communication consist of three interdependent elements, a source, messages, and a destination. Schramm's description became a common-sensical model for representing the relationship between senders and receivers mediated by the use of communication technologies. The use of communication systems to promote and direct social change, education, collective purpose and identity are morphogenic uses of information. Corrective feedback describes the process through which predictability and pattern are continuously built into the operation of many communication systems. Mass communication systems or amplification systems are sometimes called lack direct or immediate forms of feedback.
