Given the adoption and diffusion of information and communication technology in science and society, one might expect the frequency of IS-related topics and methods in scientific texts to increase over time. To quantify the proliferation of IS topics in the economic literature, we analyze titles and abstracts of articles from 17 top journals in Business and Economics over the twenty-year period from 1993 to 2012. In 2012, the percentage of articles mentioning IS-related topics was 10.6 in Business and 5.9 in Economics. In both fields, even under a conservative choice of search terms, we find a significantly positive trend in the use of IS-related terms. In Business, the share quadrupled compared to the year 1993, but flattened out in the final five years. In Economics, the positive over- all trend is even more pronounced and significant also for the final five years of the observation period.
