The gratification niches of personal e-mail and the telephone -: Competition, displacement, and complementarity

The theory of the niche predicts that a new medium will compete with established media for consumer satisfaction, consumer time, and/or consumer advertising dollars. Competition between e-mail and telephone use was measured in this study at the level of gratifications derived by consumers. Gratifications and gratification opportunities (consumers' beliefs that a medium allows them to obtain greater opportunities for satisfaction) were derived from an analysis of open-ended questions. A second sample was interviewed by telephone and rated both mediums on gratification and gratification-opportunity scales. Forty-eight percent of respondents reported using the phone less since they adopted e-mail. Results indicate that a wider spectrum of needs is being served by the telephone, whereas e-mail provides greater gratification opportunities. The results indicate competition, but also indicate that the two mediums are not close substitutes.
