Exploratory findings show a digusion of environmental movement concepts occurring through a progression from early use of specialized channels to subsequent general audience media involvement, and a content emphasis that graduates over time from relevant but unfocused information, to doctrinal content, to related substantive concerns.Sociologists are increasingly in agreement that "environmental pollution," in all its manifestations, is a clearly recognized "social problem" (19) and that "environmentalism" is a bona fide "social movement" (4, 14), with an "ideology" focused on social change. As such, environmentalism has been the subject of a wide variety of mass media coverage, and numerous studies have examined various aspects of relationships among the environmental movement and communication media (12,30). By analyzing content trends in 3,056 articles in two selected special interest (Audubon, Environment) and two general audience (Time, Saturday Review) magazines over the period from 1959 to 1979, the study reported in this article examines the roles of these two media types as well as the communication processes involved in the crystalization and diffusion of an ideology of social change (environmentalism) and the translation over time of this doctrine into a unified realm of substantive concerns.A guiding framework for this study posited that mass media organizations evolve through three basic adaptive phases-termed disambiguaGlenn C.

134Media Roles in a Social Movement tion, legitimation, and routinization-in their processing of information relevant to a maturing social cause. Gleaned from general systems theory, the involved processes correspond metaphorically to sequential phases in the growth of a system (gestation, maturation, and equilibration). Each deals with processes that seem to be characteristic of a certain temporal phase in the unfolding of a larger process-the diffusion of ideology. Thus these concepts should be seen in terms of both processes and of phases (1).Disambiguation is a process whereby the basic doctrinal tenets of an emerging social cause themselves become defined and distinguished from each other and are first manifest in the content of mass communication channels. Disambiguation should be predominant during the earliest phase of the diffusion progression and continue until the approximate point of cresting in media attention to the philosophical themes of the social movement.Legitimation is a process by which those who regulate the content for a given channel or media organization (gatekeepers) recognize various concerns pertinent to a social cause as valid topics for coverage by their particular channels.Routinization is a process whereby content relative to the movement is incorporated into the channel's operations on a fixed basis, such as through regular space, time, or personnel allocation.

A national campaign of well testing through 2003 enabled households in rural Bangladesh to switch, at least for drinking, from high-arsenic wells to neighboring lower-arsenic wells. We study the well-switching dynamics over time by re-interviewing, in 2008, a randomly selected subset of households in the Araihazar region who had been interviewed in 2005. Contrary to concerns that the impact of arsenic information on switching behavior would erode over time, we find that not only was 2003–2005 switching highly persistent but also new switching by 2008 doubled the share of households at unsafe wells who had switched. The passage of time also had a cost: 22% of households did not recall test results by 2008. The loss of arsenic knowledge led to staying at unsafe wells and switching from safe wells. Our results support ongoing well testing for arsenic to reinforce this beneficial information.
