Invocational media
Invocational media are communication technologies based on digital computers. Invocational media infrastructures assign names (or addresses) to given entities (e.g. web pages with URLs, variables in programming, disk sectors with file allocation tables), and perform events to call up these named entities from invocable domains on demand (e.g. an HTTP request, a subroutine execution, a read or write to a hard disk).
The theory of invocational media identifies the event of invocation as the defining feature (or force) of digital computing. By this theory, invocational events (invocationary acts) should be considered to be conditions for the formal and mathematical principles by which invocations are composed, and not vice versa. That is, running a computer program (which is usually considered to follow its writing) is always (paradoxically) prior to its writing.
I propose that the systems usually known as ‘interactive digital computers’ are better conceived of as ‘invocational media’.
— Chesher, C., PhD thesis (March 2001)
This theory draws on the philosophical monism and empiricism of Deleuze and Guattari and a theory of technology from actor-network theory. It offers an interpretive framework to trace unbroken connections between the lowest technical levels of computer operations through the experience of users, the conceptual frameworks in discourse, and political and economic structures, all of which are increasingly mediated by information technologies. The first order of invocation is the fetch-execute cycle, which puts command and memory into the same circuit. The second order of the invocation is the invocationary act by which users compose invocations to do things, but in doing so depend upon avocations and invocable domains that pre-exist that event. Finally, third order invocations are the concepts invoked to hold together invocational platforms: such as the metaphors of virtual reality, artificial intelligence, business information system, etc.
