ABSTRACT
Over the past four decades, Elihu Katz has made a major contribution to our understanding of the workings of mass communication by analysing mass media institutions, contents, processes and effects in their social and political contexts. Katz has taken an interdisciplinary and original approach, conducting influential research on an interconnected set of issues which have strongly influenced the agenda for media research, such as relations between individuals, groups and media institutions, the selective and active television viewer, the diffusion of innovation, media effects and media imperialism, among others.
