The new architecture of communications has two symbiotic features: an overwhelming abundance of information and communications and the emergence of narrow, ‘silos’ of information and opinion that have developed partly in response to the copious complexity available, partly because of the enhanced tools developed to navigate the variety. The weak ‘bridging’ links to many opinions that the media used to produce can be replaced by ‘strong’ personalised links to narrow views. In addition the democratic space of negotiated, re-distributive communicative space is dis-appearing. The article examines the practical working out of these tendencies in institutions by examining the new British Army doctrine which puts communications at the centre of action, and considers the ways in which silos emerge. It argues that we need new kinds of oversight. It argues that the UK tradition of extending the range of voices given platforms is a better response to the contemporary architecture of communications than the classic focus on individual freedoms of speech. It argues that the BBC, international and domestic, concerned with tone and feelings, is one of the few institutions we have constituted and built (albeit accidentally) to perfectly match this contemporary shape of communications.
