The journal ranking of the Institute for Scientific Information (ISI) is increasingly turning into an international currency for the quality of research output. More than 40 communication journals are ISI-ranked and thus labeled “major international” journals. This analysis of ISI data reveals that the attribute “international” is not always appropriate. National diversity of communication journals is very low due to a dominance of authors from English-speaking countries and U.S. authors in particular. Younger journals and journals with an explicitly stated international mission tend to be international, whereas the internationality of the affiliated organization or impact of a journal had no influence on national diversity. The results suggest that it may be desirable to clearly distinguish between national and international communication journals, to increase the number of international communication journals, and to support authors whose mother tongue is not English.
