Communication technology (CT), which involves the use of computers in private and group communication, has had a major impact on theory and research in organizational communication over the past 30 years. From the 1950s to the early 1970s, mainframe computers were seen as managerial tools in creating more centralized organizational structures. During the late 1970s, the decentralizing effect of computers on organizational communication and the impact of the new technologies on society gained more attention. Recently, the increasing centralization of the information society has been stressed once again. Real effects of increasing organizational centralization may include a power shift away from middle management and toward the power elite. How organizational members segment internal or public audiences is now increasingly based on infographic rather than demographic or psychographic variables. The concept of infographic segmentation can be extended, perhaps, to the global characterization of an organization or its subunit as showing either symbolic, ritualized, or interactive communication styles. Furthermore, to the extent that groups or individuals share a particular form of infographic culture, they indicate infographic cohorts. Consideration of theoretical questions not only makes sense of the rapid changes in communication technology, but also helps to guide them. (MM)
