Arguably, every new technology creates hidden ejfects in its environment, rearranging the social order it penetrates. Many ofthese effects are inextricably linked to ethical issues. Some are eternal issues such as censorship andfree speech, but others have new names and dimensions, and may even be new issues. Forty of these issues pertaining to the new communication technologies of the 1990s and next millennium are catalogued here. The author argues that each new communication technology either retrieves, amplifies, transforms, obsolesces, or mixes (...) ethical issues from the past or creates new issues for the future. However, as in the Ross Hume Hall (1974) effect, it is also likely there are issues yet unknown due to untested eflects of combining new technologies. (shrink)
