Communication · Executive Insight Brief · 022
The channel changes the commitment
Persistence, visibility, access, timing, and audience boundaries can reorganize work even when message content stays constant
Premise
Executives often treat channels as neutral containers and blame content when communication fails. Medium Theory asks what makes communication through one medium physically, psychologically, and socially different from another. Joshua Meyrowitz coined the label in the 1980s for a tradition including Harold Innis and Marshall McLuhan and connected it with Erving Goffman’s analysis of social situations.
The executive implication is that changing channels can change audience boundaries, memory, availability expectations, accountability, self-presentation, and authority without changing the proposition communicated. Channel selection is therefore organizational design. Leaders should trace the mechanism from a specific medium property to a changed situation and observable consequence.
