McLuhan's concept of print-dominated media culture — sequential, linear perception. Foundational to understanding how cinema disrupted information consumption.
McLuhan's concept of the Gutenberg Galaxy describes a media culture shaped by the printing press—linear, sequential, dependent on the visual processing of individual characters one after another. Those who grow up in this world absorb information as a sequence: first letter A, then B, then C. The brain trains itself for causality, logic, hierarchy. Film entered this world like an alien body.
For us as filmmakers, this is crucial: The viewer who grew up with Gutenberg expects narrative structure, clear cuts, comprehensible transitions. They want to be able to understand what is happening on screen—not to have all senses overwhelmed simultaneously in an instant. Montage works so well because it offers an ordered sequence of images, even if it's fast. Eisenstein knew this: editing is logic. We don't cut chaotically; we follow an internal sequence that the letter-conscious brain understands.
The counter-principle—electromechanical simultaneity—emerges with radio, film, and later television. McLuhan didn't necessarily see this as a break, but as a return to pre-alphabetic, sensory experience: everything at once, all senses engaged, no hierarchy. A modern viewer is immersed in this—we are all hybrid perceivers. That's why fragmented, non-linear formats work today: we are accustomed to audiovisual ambiguity.
On set, this changes the practical work: If we know that viewers are still shaped by Gutenberg thinking, we consciously plan cuts and rhythm. A long take, a black screen, a silence—these don't confuse because we contextualize them narratively. But pure sensory bombardment without context can also lose viewers. The balance between linearity and simultaneous input is the craft. Every cut, every dissolve, every sound cut is a decision between Gutenberg logic and audiovisual noise.
