Overview
“Distant Early Warning” is a title associated with Marshall McLuhan’s DEW-Line project of the late 1960s, one of the more unconventional productions of the Canadian media theorist’s most publicly celebrated years. Rather than a conventional book of continuous prose, the DEW-Line enterprise took the form of a subscription package aimed at business, professional, and general readers, of which a deck of cards bearing the “Distant Early Warning” name was a distinctive component. The whole undertaking grew directly out of one of McLuhan’s most quoted convictions: that the serious artist functions as a society’s “distant early warning system,” registering the effects of new technologies and environments before the general population becomes conscious of them.
To understand the item, it helps to understand the phrase. The “DEW Line,” or Distant Early Warning Line, was a real Cold War installation: a chain of radar stations strung across the far north of North America, principally the Canadian Arctic, built in the 1950s to detect incoming Soviet bombers or missiles and give advance warning of attack. For a Canadian thinker preoccupied with how technologies reshape human perception, this piece of continental infrastructure offered an irresistible metaphor. McLuhan repeatedly argued that art and the artist perform an analogous scanning function for culture—that where the mass of people adapt to a new medium unconsciously and belatedly, the artist detects and reports the psychic and social consequences in advance. Borrowing Ezra Pound’s image of the artist as the “antennae of the race,” McLuhan reframed art itself as an early-warning apparatus for the whole society. The DEW-Line name thus fused Cold War anxiety, Canadian geography, and McLuhan’s theory of perception into a single evocative brand.
Author and Context
Marshall McLuhan (1911–1980) was a professor of English literature who became, in the 1960s, one of the most famous intellectuals in the world. Trained in the study of Renaissance rhetoric and the Elizabethan period, he taught for most of his career at the University of Toronto, where he directed the Centre for Culture and Technology. His reputation rests on a sequence of books that turned attention away from the content of communication and toward the form of media themselves as agents of change: The Mechanical Bride (his early study of advertising and popular culture), The Gutenberg Galaxy (on the effects of print and movable type on Western consciousness), and above all Understanding Media: The Extensions of Man, the work that made his aphorisms—”the medium is the message,” the “global village,” “hot” and “cool” media—part of the common vocabulary of the decade. In the later 1960s he collaborated on illustrated, typographically playful books such as The Medium Is the Massage and War and Peace in the Global Village, which carried his ideas to a still wider audience.
The DEW-Line project belongs to this period of maximum celebrity, roughly the second half of the 1960s, when McLuhan had become a media personality courted by advertisers, executives, broadcasters, and universities. Having argued that electric media were dissolving the linear, sequential habits of the print era in favor of simultaneous, mosaic, “all-at-once” patterns of perception, McLuhan increasingly sought forms of publication that would embody rather than merely describe that shift. His picture-and-text collaborations were one expression of this impulse; the DEW-Line package, with its non-linear, modular design and its readiness to be consumed in fragments, was another. It reflected his conviction that the book itself, as a fixed, sequential object, was an artifact of a passing typographic age.
The DEW-Line Enterprise and the “Distant Early Warning” Cards
The DEW-Line was conceived as a periodical service rather than a single volume. Under the DEW-Line banner McLuhan issued a newsletter directed largely at the corporate and managerial world—readers who wanted access to the era’s most talked-about ideas man and to his diagnoses of a rapidly changing communications environment. The premise was that executives and decision-makers, like a nation defending itself, needed early warning of the disruptions that new technologies would bring to their industries and organizations; McLuhan’s cultural radar would supply it. The service thus married McLuhan’s theory of the artist-as-sensor to a practical, almost consultative promise of foresight.
The “Distant Early Warning” cards were a striking part of this package: a deck presented in the format of ordinary playing cards but repurposed as a device for provoking thought. Rather than functioning simply as a game, the deck was designed as a tool for lateral, non-linear idea generation—shuffled and drawn to jolt the user out of habitual, sequential reasoning and into fresh combinations and juxtapositions. This aligned exactly with McLuhan’s larger argument that creative insight arises from pattern recognition and the collision of apparently unrelated fields rather than from step-by-step logic. In using a deck of cards to externalize and randomize the process of thinking, the DEW-Line deck anticipated a genre of aleatory creativity aids that would later become familiar in design and the arts.
The whole project was characteristic of McLuhan in refusing the boundary between serious cultural theory and playful, commercial, gadget-like form. Where a conventional scholar might have published his warnings as a monograph, McLuhan chose a hybrid object—part subscription bulletin, part game, part corporate briefing—that performed his thesis about the obsolescence of the linear book even as it delivered his ideas. The medium, in the DEW-Line’s case as in so much of his work, was meant to be inseparable from the message.
Themes and Significance
The governing theme of the DEW-Line material is the one that runs through all of McLuhan’s mature work: that environments created by new technologies act upon human beings largely below the threshold of awareness, and that the task of the perceptive observer is to make those hidden effects visible. The name “Distant Early Warning” condenses his belief that culture, like a continent, needs sentinels posted at its far edges—artists and analysts who can detect the approach of change while there is still time to respond. The corollary, congenial to his business audience, was that those who cultivated such awareness could anticipate and even shape transformations that would blindside everyone else.
Within McLuhan’s body of work, the DEW-Line project is a minor but revealing production. It does not carry the theoretical weight of The Gutenberg Galaxy or Understanding Media, and it is far less widely read than his major books. Its significance lies rather in what it shows about McLuhan’s method and ambitions at the height of his fame: his eagerness to experiment with the physical form of communication, his willingness to engage directly with the commercial and corporate world, and his conviction that the ideas he had developed for cultural criticism could be turned into practical instruments for navigating a media-saturated future. As an artifact, “Distant Early Warning” survives chiefly as evidence of that experimental, boundary-crossing side of McLuhan—the theorist who not only wrote about the reshaping of perception by media but tried to design objects that would enact it.
