Intermedia agenda setting effects between Internet bulletin boards and traditional news media in U.S. and Korean presidential campaigns

This comparative research looks at intermedia agenda-setting effects between Internet bulletin boards and traditional news media, such as daily newspapers and broadcasting, in both the United States and Korea. By examining this intermedia relationship and the flow of influence by Internet bulletin boards on traditional media during presidential campaigns in the two countries, this dissertation study attempts to extend our knowledge of intermedia agenda-setting research. In addition, it also investigates, in reverse, the effects of daily newspapers and broadcasting on Internet bulletin boards. Finally, attention is given to different types of discussion cultures in the two countries. Results of this dissertation research indicated that there are intermedia relationships between Internet bulletin boards and traditional news media, such as newspapers and broadcasting, at the first and second levels of agenda setting using cross-lagged correlation comparisons. More specifically, at the first level of agenda setting in the United States, the results explained only the influence of newspapers on Netizen opinions posted on Internet bulletin boards. In summary, the results concerning issue agenda in the United States indicate that the U.S. Netizen concentrates more on the issue agenda of newspapers than of broadcasting. In the second level of agenda setting in the United States, cross-lagged correlation comparisons not only indicated the influence of both newspapers and broadcasting on opinions posted on Internet bulletin boards, but they also clarified it in this research. Formerly, there was no attempt to examine attributes of the intermedia agenda-setting functions of the U.S. media. This research now provides an explanation of the apparent relationship between traditional media and the Internet. At the first level of agenda setting in Korea, the result of the cross-lagged correlation suggested that Korean newspaper and broadcasting issue agenda influenced Netizen opinions on Internet bulletin boards. As the result of second-level agenda setting in Korea showed earlier, cross-lagged correlation comparisons presented intermedia agenda-setting functions between both newspapers and broadcasting, and Internet bulletin boards with each other. These findings contrast with results in the United States.
