Organizational communication is a subfield of the larger discipline of communication studies. Organizational communication, as a field, is the consideration, analysis, and criticism of the role of communication in organizational contexts. Its main function is to inform, persuade and promote goodwill. The flow of communication could be either formal or informal. Communication flowing through formal channel's are downward, horizontal and upward whereas communication through informal channel are generally termed as grapevine.HistoryThe field traces its lineage through business information, business communication, and early mass communication studies published in the 1930s through the 1950s. Until then, organizational communication as a discipline consisted of a few professors within speech departments who had a particular interest in speaking and writing in business settings. The current field is well established with its own theories and empirical concerns distinct from other fields.Several seminal publications stand out as works broadening the scope and recognizing the importance of communication in the organizing process, and in using the term "organizational communication". Nobel Laureate Herbert A. Simon wrote in 1947 about "organization communications systems", saying communication is "absolutely essential to organizations". W. Charles Redding played a prominent role in the establishment of organizational communication as a discipline.
