The attention of most commentators on globalisation is on powerful intergovernmental organisations and giant corporations; but the myriad economic and cultural activities of transnational groups that are neither government-nor corporate-based constitute a distinct ‘globalisation-from-below’ (Falk 1993; also see Brecher, Costello and Smith 2000). This form of globalisation is characterised by the complex formal and informal intercontinental networking of associations, many of which are loosely organised. The planetary connections produced by transnational migrations contribute significantly to globalisationfrom-below.1 This human activity is not a recent development; it has been occurring for many centuries and has led to the growth of diasporas linked by social characteristics like ethnicity, language, religion and culture. These groups have been developing intercontinental networks of communication that use a variety of media that include mail, telephone, fax, film, audiotape, videotape, satellite television and the Internet. The social implications of such diasporic ‘mediascapes’ (Appadurai 1996) are the subject of scholarly debate and are under discussion in this volume. Its authors analyse the uses of media by various transnational communities originating and residing in six continents.
