An examination of home internet and mobile device use in the U.S.

It is important to understand the determinants of the extent and types of activities performed by home Internet users and by mobile device users, as well as the interactions between these modes of usage. Few studies have looked at the interactions between these two channels of digital com-munication. While most prior research has been based upon surveys of attitudes toward and inten-tions to use a technology (and lack a final link to actual usage), in this study, the extent of actual home Internet use, mobile device use, and the simultaneity between these modes of usage are ex-amined. We find that, overall, mobile device use is enhanced by home Internet use, while the two act as substitutes in the case of advanced and sensitive applications.
