Diamond Shreddies Myth: Why Marketing Gurus Miss the Joke

As of 2008, Shreddies had been one of Canada’s most popular breakfast cereals for nearly seventy years. First introduced in 1939, the lattice-woven whole-wheat squares, similar to Chex in the US were a household fixture. They were reliable and nutritious. They were also undeniably square. Then, Kraft and advertising agency Ogilvy & Mather announced a radical, industry-shaking transformation! They were replacing the classic square with “Diamond Shreddies.” The multi-million-dollar ad rollout had all the hallmarks of a breathless, self-important corporate rebrand. Deadpan spokespeople looked into the camera to tout years of intense research and development. Slick television spots featured “focus groups” where consumers tasted a traditional square piece, then sampled a piece rotated 45 degrees, marveling at how the new diamond geometry delivered a “crispier,” “snappier,” and vastly superior eating experience.

On supermarket shelves across Canada, shiny new boxes of “Diamond Shreddies” appeared alongside the traditional squares. Eventually, the brand even released a “Combo Pack”, a box proudly containing both squares and diamonds mixed together, offering “indecisive” shoppers the best of both worlds. It was a resounding success.

The Corporate Playbook Being Parodied

To understand why the stunt worked, it helps to look at the exact corporate behavior Ogilvy & Mather was mocking. By the late 2000s, legacy food brands faced a classic industry dilemma:

The Core Audience: Loyal, older consumers who buy the product every week and will revolt if you alter the recipe by even one percent.
The Boardroom Mandate: Corporate executives demanding double-digit growth and “disruption” to attract younger demographics.

When a brand is terrified to touch its actual recipe, the standard agency response is a desperate cosmetic refresh. A company will subtly tweak a font, add a wave to a box, or introduce a “new and improved” claim that amounts to virtually nothing, then spend tens of millions of dollars pretending they have reinvented the wheel.

As the creative team at Ogilvy recognized, everyone in the grocery aisle sees right through this song and dance. Rather than running another timid, self-serious redesign, they chose to lean directly into the absurdity of the corporate relaunch.

Legend (and agency lore) has it that during an Ogilvy brainstorming session, a junior copywriter/intern pitched the idea as a joke. However, the agency saw something more than a joke in the idea. If corporate branding is fundamentally about pretending nothing is something, why not take that logic to its ultimate extreme? Instead of spending millions retooling a factory or alienating loyal buyers with an artificial recipe tweak, they would deliver the ultimate corporate “innovation”: take the exact same cereal and rotate it 45 degrees.

The Satire Everyone Got—Except the Marketing Industry

To anyone living in Canada at the time, the premise was unmistakable. It was an affectionate, deadpan piece of national meta-satire. Post wasn’t secretly trying to convince breakfast eaters that their factories had undergone a high-tech overhaul. They were inviting consumers to participate in an absurd inside joke. Canadians bought the boxes because they thought turning a square into a diamond was genuinely funny.

Yet in the years since, the story of Diamond Shreddies has taken on a bizarre second life. In business books, marketing keynotes, and internet trivia channels, the campaign is routinely presented through one of two distorted lenses:

The Cynical Hoax: Modern commentary channels often list it as an example of deceptive corporate greed, treating the campaign as a real attempt to hoodwink gullible consumers with a 45-degree angle.
The High-Minded Psychological Masterclass: Marketing authors frequently over-analyze the campaign as a highly technical exercise in behavioral economics, framing the choice between “Square” and “Diamond” as a genuine psychological conundrum designed to manipulate consumer choice architecture.

Both miss the real point. You don’t need to fool customers with advertising. You only need to capture their attention and sometimes, laugh along with them. If the Shreddies story is anything, it’s a study in how marketing culture continually invents complex psychological theories to explain simple, shared humor.

Similar Campaign: The “Left Twix vs. Right Twix” Cold War: In 2012, candy giant Mars and agency BBDO faced a dilemma similar to Shreddies. How do you advertise a mature, unchangeable chocolate bar without running another tired “now with more crunch” campaign? Their solution was pure corporate theater: The Great Twix Split.

The campaign invented a humorous backstory about two fictional rival inventors, Seamus and Earl, who feuded so bitterly over packaging and chocolate-cascading techniques that they split the company into two separate, ideologically opposed factories: “Left Twix” (flowing caramel on crunchy cookie) and “Right Twix” (cascading caramel on crisp cookie).

Mars rolled out distinct packaging, dueling trade-show booths, and mockumentaries urging consumers to pick a side. Nobody buying a candy bar actually believed the twin cookies came from separate rival compounds, of course. They bought into the joke. By turning a non-existent difference into a full-scale parody of corporate feuds, Mars drove a double-digit sales lift on a product that hadn’t changed a single ingredient. Like Shreddies, this dialogical approach, treating customers as equal participants, is more than just a clever joke. It’s a valid and evolving form of marketing communication.

The “Conundrum” Fallacy: When Experts Miss the Punchline

The fundamental blind spot in marketing literature is the refusal to view consumers as self-aware human beings. To modern marketing theorists and business authors, the public cannot simply be in on a joke. They must be passive, malleable test subjects governed by subconscious triggers and behavioral mechanics.

In business books analyzing Diamond Shreddies, authors routinely frame the grocery aisle experience as a high-stakes psychological puzzle: How will the bewildered shopper navigate the cognitive dilemma between the familiar square and the novel diamond?!

This framing completely misses the reality of human behavior:

Participation vs. Confusion: When shoppers stood in the cereal aisle looking at a box of “Original Square” next to “New Diamond”, and eventually the “Combo Pack”, they weren’t experiencing choice paralysis or psychological dissonance. They were chuckling. They bought the cereal precisely because Post treated them like smart, witty adults. Buying a box was an act of joining in on a national prank.
The “Guru” Superiority Complex: Marketing consultants and authors love feeling like they hold the keys to an esoteric behavioral science that ordinary “civilians” cannot comprehend. If they admit that Canadian consumers simply recognized the deadpan satire and bought the cereal for a laugh, there is no psychological magic to sell in a six-figure seminar. They have to invent a narrative of subconscious manipulation to validate their own industry.
Analyzing the Satire with the Fluff It Spoofed: The supreme irony of these marketing critiques is that the Diamond Shreddies campaign was an overt parody of the very corporate jargon now used to analyze it. It mocked high-minded rebrands, pretentious R&D claims, and focus-group theater. When a marketing book solemnly analyzes the “behavioral choice architecture” of rotating a wheat square 45 degrees, it becomes the exact punchline Ogilvy & Mather wrote in 2008.

Miracle Whip and the “Love It or Hate It” Civil War: Most condiment marketing suffers from a generic disease. They try to convince 100% of shoppers that their spread is a universally beloved, wholesome staple. In 2011, Kraft and agency McGarryBowen did the unthinkable with Miracle Whip: they built an entire multi-million-dollar campaign around the fact that millions of people find the product repulsive.

Rather than running focus-group ads claiming that Miracle Whip was “new and improved,” they ran television spots featuring celebrities and everyday eaters openly gagging, grimacing, and describing it as “tangy trash,” juxtaposed against hardcore loyalists who treated it like nectar. They even launched an “Open Letter to the Haters.”

By openly abandoning corporate perfection and leaning into the divisive joke of their own polarizing flavor profile, Miracle Whip drove double-digit sales lifts among their core base by proving the brand had a sense of humor about its own reputation.

The “Executive Permission” Game vs. The Guru Lecture Circuit

To understand why this happens, it helps to separate the people who actually make advertisements from the “gurus” who sell marketing theory.

In typical corporate history, risk-averse boardrooms look for executive permission. Facing stagnant sales, executives are often terrified of making a bold move on their own. They hire high-priced consultants not for creative genius, but for bureaucratic cover. When a consultant delivers a thick binder wrapped in psychoanalytic jargon, whether it was Ernest Dichter claiming cake mix needed a Freudian “gift of fertility,” or Louis Cheskin claiming the McDonald’s Golden Arches represented the “nourishing breasts of Mother McDonald”, executives finally feel safe to pull the trigger. If it works, the consultant takes credit. If it fails, the executive points to the consultant’s report.

With Diamond Shreddies, Post and Ogilvy sidestepped that corporate permission game entirely. Working advertising creatives understand the raw power of a great joke. They didn’t need a 200-page psychological dossier. What they needed were the creative chops and logistical discipline to execute an absurd bit across television, print, and physical grocery shelves. Instead, the true desperation came later, from the marketing lecture circuit.

For business-school professors, keynote speakers, and pop-marketing authors whose entire livelihood depends on selling the illusion of predictive human manipulation, a campaign like Diamond Shreddies is terrifying. It pulls back the curtain on the industry’s biggest magic trick. If a legacy brand can generate double-digit sales growth by only rotating a wheat square 45 degrees and laughing along with the public, then the entire apparatus of “behavioral consumer engineering” looks like the emperor’s clothes.

So, the pundits do what they always do. They retrofit the joke into a pseudoscientific psychological framework. They take a dry piece of Canadian satire and rewrite it as complex cognitive science, because in the guru economy, the only thing more dangerous than a failed campaign is an ad that worked simply because it was funny.

The Anti-Pattern: When the Joke Is on the Customer

The success of campaigns like Diamond Shreddies and the Left vs. Right Twix split hinges on a single unwritten rule: the audience must be invited into the joke from day one. When brands lose the creative chops to maintain that delicate balance, comedic marketing quickly degrades into cynical stunt work.

A prime modern contrast was IHOP’s 2018 “IHOb” (International House of Burgers) campaign. Rather than establishing a transparent, self-aware piece of corporate satire, the company pretended to legally abandon its sixty-year breakfast identity, letting genuine confusion, customer frustration, and online mockery fester for weeks before revealing it was just a burger promotion.

While the stunt generated a temporary spike in quarterly burger sales, it violated the social contract of good comedic advertising. Instead of laughing with the audience, the brand made the customer the punchline of a corporate bait-and-switch. Pulling off a comedic campaign requires more than just an absurd idea! It requires the creative restraint and sound narrative planning required to entertain your audience rather than treat them as props in a PR ambush.
