Channel Control

channel-control measures structural power over the channels through which knowledge flows — control of the agenda channels that decide which knowledge counts (venues, ranking/accreditation machinery) and the physical data channels others depend on (orbital/comms infrastructure). The structural question is: who controls the channels and infrastructure through which knowledge is communicated, and on what terms? — not how many universities, students, or satellites a country has. The metric spans the academic agenda channels and the orbital/data channels — one structural lever over two infrastructures.

Strange makes channel-control a defining clause of the knowledge structure, and explicitly treats satellites as a channel, not a trophy:

• the definition: a knowledge structure "determines what knowledge is discovered, how it is stored, and who communicates it by what means to whom and on what terms" (Strange 1994, p.121)
• authority on "those controlling in any way the channels by which knowledge, or information, is communicated" (Strange 1994, p.121) and on those "acknowledged by society to be possessed of the 'right', desirable knowledge" (Strange 1994, p.121)
• satellites as the channel: "the two key technical innovations… sophisticated computers and the development of electronic communication by means of earth-orbiting satellites" (Strange 1994, p.225) — infrastructure of communication, not a prestige count.
• satellites as a contested channel states race to control: "The superpowers, significantly, were the first to launch earth-orbiting satellites. They were also the first to develop high-powered computers for use in space and for military intelligence and battlefield communication" (Strange 1994, p.134) — orbital/comms infrastructure as the channel, scored by control not by trophy count.
• the exclusion lever: power "lies as much in the negative capacity to deny knowledge, to exclude others" (Strange 1994, p.119) — who can deny orbital/spectrum/agenda access.
