Based on research in London and Trinidad, this book shows how 'always-on' webcam is becoming an entirely different phenomenon from the initial use of webcam as a videophone. Webcam is examined within the framework of 'polymedia' - that is, the new environments created by the simultaneous presence of a multiplicity of communication technologies - and used to exemplify a theory of attainment that accepts media technologies as aspects of, rather than detracting from, our basic humanity.
