Marketing During World War II: When Advertising Became a Weapon

How governments and brands sold sacrifice, secrecy, thrift and the promise of a better tomorrow

In 1942, a successful advertisement might tell you not to buy anything.

It might ask you to repair your old clothes, grow potatoes in your garden, stop gossiping on the bus, collect scrap metal or hand your savings to the government.

The advertiser might not even be a company.

It might be the Ministry of Information.

And the product being sold was victory.

Marketing Without a Marketplace

The Second World War disrupted almost everything marketers normally rely upon.

Factories stopped producing household goods and started producing aircraft, weapons and military equipment. Raw materials were controlled. Food, fuel and clothing were rationed. Products disappeared from shelves, while prices and distribution were increasingly managed by the state.

Demand was no longer the main problem.

Supply was.

This created an unusual challenge for commercial brands. How do you advertise chocolate when there is not enough chocolate to sell? How do you maintain customer loyalty when shoppers have little choice over what they can buy?

Meanwhile, governments faced the opposite problem.

They needed millions of people to change their behaviour quickly.

Civilians had to accept rationing, protect sensitive information, grow food, enter unfamiliar jobs, lend money to the government and endure restrictions with as little complaint as possible.

Marketing had stopped being primarily about selling products.

It had become a tool for organising society.

Britain’s Biggest Advertising Agency

Britain’s Ministry of Information became one of the most powerful communications organisations in the country.

It was responsible for government publicity, wartime information, censorship and propaganda. Its campaigns appeared across posters, newspapers, leaflets, exhibitions, radio broadcasts and films.

These were not simply public announcements.

They were coordinated behaviour-change campaigns.

The government identified a problem, selected an audience, created a memorable proposition and distributed it repeatedly through the available media.

In other words, it did marketing.

Dig for Victory

Before the war, Britain imported enormous quantities of food. Enemy attacks on merchant shipping threatened those supply lines, making domestic production a national priority.

The solution was marketed through one of the period’s most memorable slogans:

Dig for Victory.

Gardens, parks, sports grounds and other available spaces were converted into vegetable plots. Posters showed healthy produce emerging from freshly dug soil. Advice was distributed about what to grow and how to grow it.

The campaign did not attempt to explain every detail of Britain’s food supply problem in a single poster.

It gave people one clear action.

Dig.

The brilliance was in the framing. Growing vegetables was not presented merely as gardening or personal thrift. It became a patriotic act.

Every potato was apparently taking a small but meaningful swing at Hitler.

Imperial War Museums records that Britain had imported around 55 million tons of food each year before the war, demonstrating why food production became such an important part of the home-front campaign.

Make Do and Mend

Clothes rationing was introduced in Britain in June 1941. Fabric, labour and manufacturing capacity were needed elsewhere, so civilians were encouraged to make their existing clothing last longer.

The resulting campaign was another masterclass in compressed communication:

Make Do and Mend.

The slogan contained the problem and the solution in four words.

Government films, posters, pamphlets and classes taught people how to repair damaged clothing, reuse material and transform old garments into something wearable.

The message was practical, but it also carried a moral judgement.

Throwing something away was no longer merely wasteful. It was letting the side down.

The campaign turned domestic sewing into participation in the national war effort. It was sustainability marketing several decades before brands began congratulating themselves for replacing a plastic lid with a slightly different plastic lid.

The Ministry of Information even produced instructional films showing people how to repair and reimagine their clothes.

Careless Talk Costs Lives

Other campaigns relied less on pride and more on fear.

Careless Talk Costs Lives warned civilians that apparently harmless conversations could reveal information useful to the enemy.

The campaign could easily have become a collection of dense security instructions.

Instead, artist Cyril Kenneth Bird, better known as Fougasse, used simple cartoons and dark humour.

In one design, a man speaks inside a telephone box while caricatured versions of Adolf Hitler listen from every direction.

The message was absurd enough to attract attention but serious enough to be remembered.

It understood an important advertising truth: people frequently ignore instructions, but they remember a joke.

The campaign also created a simple mental trigger. Before discussing something sensitive, people were encouraged to imagine that the enemy might be listening.

That is not simply awareness.

It is behavioural design.

The Poster That Barely Existed

No discussion of British wartime marketing can ignore Keep Calm and Carry On.

Unfortunately, wartime Britain largely did ignore it.

The poster was designed before the war as part of a series intended to reassure the public during a major national crisis. Millions of copies were reportedly printed, but the design was never officially approved for widespread public display.

It did not become the defining slogan of wartime Britain.

It became the defining slogan of British gift shops roughly 60 years later.

The poster was rediscovered in 2000 and subsequently reproduced on mugs, T-shirts, cushions, tea towels and almost every object capable of remaining still long enough to receive some white lettering and a crown.

According to Imperial War Museums, it was never officially sanctioned for display.

This makes it a fascinating example of retrospective brand building.

Modern culture selected one image from the archive and turned it into a summary of an entire national character: restrained, resilient and mildly irritated.

America Puts Madison Avenue to Work

When the United States entered the war, its advertising industry was mobilised alongside its factories.

The War Advertising Council, established in 1942, brought agencies, media owners and advertisers together to support government communications.

Campaigns encouraged Americans to purchase war bonds, conserve resources, avoid sharing sensitive information and enter war-related employment.

The American Office of War Information produced thousands of posters and worked with newspapers, magazines, radio stations, film studios and outdoor advertising companies.

Rather than dismantling the commercial advertising system, the government redirected it.

Audience reach, creative talent and media space were converted into national infrastructure.

The modern Ad Council grew from this wartime collaboration, demonstrating how a temporary communications response became a permanent part of American public-service advertising.

Rosie the Riveter and the Marketing of a New Workforce

One of America’s biggest challenges was convincing more women to enter industries previously dominated by men.

The answer was a campaign built around strength, competence and patriotism.

Rosie the Riveter became the symbolic face of millions of women working in factories, shipyards and other essential roles.

She was not marketed as someone reluctantly filling a vacancy.

She was helping win the war.

This repositioning mattered.

The work could be difficult, unfamiliar and socially disruptive. Advertising transformed it into evidence of national loyalty and personal capability.

The famous We Can Do It! poster is now closely associated with Rosie, although it was originally produced for internal use by Westinghouse and was not the enormous wartime cultural icon it later became.

Like Keep Calm and Carry On, its modern fame tells us almost as much about later generations as it does about the war itself.

Brands Had to Advertise Products Nobody Could Buy

Commercial advertising did not disappear during the war.

It changed its purpose.

Research into British wartime advertising shows that food, drink and confectionery brands used advertisements to explain shortages, apologise for limited availability, clarify rationing arrangements and ask customers for patience.

Some brands advertised not to create immediate sales but to protect future goodwill.

The message was effectively:

We are still here. We remember you. Please remember us when normal life returns.

This was brand marketing detached from short-term conversion.

Companies understood that disappearing from public view completely could be dangerous. When products returned, customers might choose whichever name remained most familiar.

Brands therefore promoted their wartime contribution, offered practical advice and positioned shortages as a shared national inconvenience rather than a business failure.

Instead of saying, “Buy our product”, they said, “We are doing our bit too”.

From Competition to Cooperation

Wartime controls also weakened some of the distinctions between competing products.

Production was simplified. Distribution was restricted. Certain goods were pooled or standardised to conserve resources and increase efficiency.

Under normal conditions, brands compete by emphasising difference.

During the war, difference could be treated as an unnecessary luxury.

For marketers, this created an uncomfortable reality. Product features, packaging and availability might all be outside the company’s control.

The remaining source of differentiation was often reputation.

Brands could not always promise a better product today.

They could promise to be a company worth returning to tomorrow.

Disney Goes to War

Entertainment brands were also recruited.

Disney produced films, illustrations and campaign materials for the American war effort. Familiar characters were used to communicate messages about food, conservation, taxes and military service.

This benefited the government because trusted characters could make serious instructions more accessible.

It also strengthened Disney’s association with American identity and patriotism.

The arrangement demonstrated the power of what would now be called an established brand platform.

People were more receptive to difficult messages when they arrived through characters and stories they already knew.

Mickey Mouse had accumulated enough brand equity to be temporarily deployed as a government communications channel.

Propaganda Is Marketing With the Stakes Turned Up

The relationship between public relations and propaganda remains complicated, particularly because wartime propaganda frequently used distortion, stereotyping and dehumanisation.

But its mechanisms remain familiar to marketers:

• A clearly defined audience.
• A specific desired behaviour.
• A simple and repeatable proposition.
• Powerful emotional framing.
• Consistent visual communication.
• Distribution across multiple channels.
• Repetition until the message becomes culturally familiar.

The main difference was not the toolkit.

It was the objective and the scale.

A commercial campaign might encourage someone to change toothpaste.

A wartime campaign might encourage them to change their occupation, diet, spending habits and willingness to tolerate government restrictions.

The Dark Side of Simplification

The simplicity that made wartime campaigns effective also made them dangerous.

Complex political and military realities were reduced to heroes, villains, slogans and symbols.

The enemy became an easily recognisable caricature. National identity was presented as a single shared experience, even when people’s actual experiences differed dramatically.

Propaganda did not merely communicate the war.

It decided how the war should be understood.

This remains an important ethical warning for marketers.

A simple message is not necessarily an honest one.

Clarity can help people understand reality, but it can also remove inconvenient parts of it.

What Marketers Can Learn From World War II

1. Start With the Behaviour

Many wartime campaigns had exceptionally clear objectives.

Grow food. Repair clothes. Buy bonds. Join the workforce. Keep quiet.

Modern campaigns often disappear beneath vague objectives such as “drive engagement” or “increase awareness”.

Awareness of what?

Engagement leading where?

Wartime marketers usually knew exactly what they wanted people to do next.

2. Turn Individual Action Into Group Identity

Growing carrots was framed as fighting the enemy. Factory work became patriotism. Saving money became funding victory.

The campaigns connected small personal actions to a much larger shared purpose.

This remains one of the strongest tools available to marketers. People are more likely to act when the action says something meaningful about who they are and which group they belong to.

3. Simple Does Not Mean Boring

“Dig for Victory” and “Make Do and Mend” were short, but they were not empty.

Each contained an action, a purpose and an implied story.

As the most effective political slogans continue to demonstrate, the best slogans do not merely sound good.

They compress strategy.

4. Humour Can Carry Serious Messages

The Fougasse security posters proved that humour could make an unpleasant instruction more memorable.

The joke attracted attention. The warning remained afterwards.

Brands often avoid humour when the subject is serious, but seriousness and dullness are not the same thing.

5. Brand Building Matters When Sales Are Impossible

Wartime companies continued communicating even when products were unavailable.

They understood that marketing was not only a mechanism for generating this week’s transactions.

It also maintained memory, trust and future preference.

Stopping all brand activity during difficult conditions may protect a short-term budget while creating a much larger long-term problem.

6. Context Changes the Meaning of Everything

A poster encouraging people to reuse clothing might look ordinary today.

During wartime shortages, it represented necessity, sacrifice and national survival.

Messages do not exist independently of the moment in which they appear.

Good marketers understand the cultural context around a campaign rather than simply placing a clever line into it.

The MMC View

The Second World War demonstrated why every marketer should be a student of marketing history: marketing was far more powerful than simply selling soap, cigarettes or breakfast cereal.

It could organise labour, shape public morale, change diets, encourage secrecy and persuade millions of people to tolerate extraordinary restrictions.

Governments borrowed the tools of commercial advertising because those tools worked.

Brands, meanwhile, learned how to maintain relationships when products were scarce and immediate sales were impossible.

The best wartime campaigns were ruthlessly focused. They gave people one action, connected it to a shared purpose and repeated it until it became part of everyday language.

The worst campaigns showed the danger of the same approach: oversimplification, manipulation and the removal of anything that complicated the preferred story.

Marketing did not win the Second World War.

But it helped persuade millions of people that their gardens, savings, factory shifts, old trousers and carefully controlled conversations were part of it.

And that might be one of the greatest marketing achievements in history.

TL;DR

• During the Second World War, governments used advertising techniques to influence civilian behaviour on an unprecedented scale.
• British campaigns such as “Dig for Victory”, “Make Do and Mend” and “Careless Talk Costs Lives” gave audiences clear and memorable actions.
• “Keep Calm and Carry On” was designed before the war but was never officially approved for widespread display.
• American advertising agencies and media owners supported campaigns involving war bonds, rationing, conservation and workforce recruitment.
• Commercial brands continued advertising through shortages to maintain customer trust and protect future demand.
• The central lesson is that effective marketing connects a simple behaviour to a much larger shared purpose.
