The purpose of this article is to recover Williams as a major theoretical inspiration for the social sciences, specifically, as the inaugurator of what might be regarded as a research paradigm, cultural materialism. In the first section, Williams's encounter with the discipline of sociology is traced and distinguished as a critical alternative to the presently ascendant - at least in the USA - neo-Durkeimian school of cultural sociology'. In the second section, his cultural-materialist programme is proposed as a powerful analytical framework for the study of culture and society today. In the final section, a key concept of Williams's cultural materialism, mobile privatization, is selected illustratively and proposed as a powerful analytical tool for studying the production and technological mediation of typical modes of communicative sociality in the early twenty-first century.
