Plan: The Erasable Billboard for Girls’ Education

A large illustrated billboard appears in a busy city square. People donate, receive a simple eraser, and start rubbing away the artwork. As the top layer disappears, a second illustration is revealed underneath, shifting the story from girls working to girls going to school.

Plan has reported that tens of millions of girls worldwide are pushed into work instead of education, while in many less privileged countries boys are more likely to get access to schooling. To spark action, Plan and CLM BBDO created an erasable billboard with an illustration designed to be removed to reveal another illustration underneath. The billboard ran in central locations in Paris and Berlin. Passers-by were invited to donate in exchange for an eraser, then use it to change what the billboard showed.

Why the “erasable” mechanic is so strong

The mechanism does two jobs at once. It raises money, and it makes the issue understandable without explanation. The before-and-after is literal. Work disappears. School appears. The donor is not only informed. The donor performs the change. Cause-led campaigns should treat participation as the message, not a bonus layer.

Extractable takeaway: When the donor completes the transformation with their hands, the message becomes a memory and the donation feels consequential.

Definition-tightening: the eraser is not a gimmick. It is the interface, meaning the simple physical tool that gives the donor viewer control over the story. Because the act of erasing creates ownership, it makes someone more likely to donate, talk about it, and remember it.

In social-impact fundraising, participatory outdoor media can turn a small donation into a visible act of change that people feel in their hands.

The real question is whether your donation ask feels like participation or just passive sympathy.

What Plan is really buying

This is a public proof of participation. Instead of asking people to “care” in private, it makes caring visible, social, and shared. Every person who erases becomes a live endorsement that the issue matters enough to stop and act.

Steal this pattern: make giving tactile

  • Make the transformation physical. A tangible before-and-after beats a poster full of statistics.
  • Use the donation as the trigger. The action should only unlock after contribution, not before it.
  • Let participation create the content. The billboard changes because people change it.
  • Design for bystanders. Watching others erase is part of the persuasion.

A few fast answers before you act

What is the “Erasable Billboard” idea?

An illustrated billboard designed to be physically erased. Donors receive an eraser and reveal a second image underneath, shifting the story from girls working to girls going to school.

Why exchange a donation for an eraser?

Because it turns giving into an action. The eraser is a simple reward, but more importantly it is the tool that lets the donor create the transformation themselves.

What makes this more effective than a standard charity billboard?

It is participatory and observable. The public sees the billboard changing in real time, which builds social proof and makes the issue easier to grasp.

What is the main emotional lever?

Viewer control. The donor does not only learn about the problem. The donor performs a symbolic solution in front of others.

What is the biggest execution risk?

If the transformation is not instantly readable, people will not engage. The before-and-after needs to be obvious from a distance and satisfying up close.

Heineken Carol Karaoke

What if you were singing holiday carols to a few friends at a karaoke bar, when suddenly your performance became a concert broadcast before thousands on the Jumbotron at a professional basketball game, in Times Square and on the screens of nearly every New York City taxicab. Would you keep singing?

That is the setup behind Heineken’s Carol Karaoke. It starts as a small, friendly singalong, then flips into a “will you or won’t you” decision in seconds. Keep going and you are suddenly performing for strangers at scale. Stop and you walk away from the moment.

How the stunt works

The mechanism is deliberately clean. Invite people to sing. Reveal the twist. Put a choice in front of them with no time to overthink. The broadcast layer is what raises the stakes, but the real content is the decision itself. Because the choice arrives before people can script themselves, the reaction reads as real, which is why the clip holds attention. The real question is whether you keep singing once the room suddenly becomes the city.

It is also built for the social era without relying on a hashtag to do the work. The reaction is the story. The story becomes the share unit. Here, the “share unit” is the few seconds where the singer realizes the stakes and chooses.

In big-city holiday campaigns, the fastest route to earned attention is a simple public challenge that people can imagine themselves facing.

Why it lands

Karaoke is already a controlled embarrassment. The campaign simply stretches that discomfort from “friends in a booth” to “a city watching”. That tension creates instant empathy and instant curiosity, because nearly everyone knows what it feels like to sing badly, and nearly everyone has imagined what it would feel like to be exposed. Heineken positions itself as the catalyst for crossing that line, not the judge of the performance.

Extractable takeaway: If you want a stunt to travel, engineer one visible, time-pressured choice that viewers can feel, then make the brand the enabler of that choice, not the evaluator.

Business intent

This is branded entertainment built around social courage. It connects Heineken with celebration behavior, and it manufactures a holiday moment that people will retell, because the premise is easy to repeat and the outcome is emotionally satisfying.

Steal these levers from Carol Karaoke

  • Use a decision, not a slogan. Put real choice in the frame and you get real reaction.
  • Make the twist explainable in one sentence. If the idea cannot be retold instantly, it will not travel.
  • Raise stakes with environment, not complexity. Big screens and public broadcast do more than extra rules.
  • Cast ordinary people. Relatability is what turns “a stunt” into “I can picture myself there”.

A few fast answers before you act

What is Heineken Carol Karaoke?

It is a surprise karaoke activation where people singing holiday carols are suddenly offered a choice. Keep singing and be broadcast publicly to a much larger audience, or stop and walk away.

Why does the “will you or won’t you” structure work?

Because the content is the decision under pressure. That creates tension, authenticity, and a clear emotional arc that viewers follow in seconds.

What role do out-of-home screens play in the idea?

They turn a private performance into a public moment instantly. The scale shift becomes the stakes, and those stakes are immediately legible to anyone who has ever felt stage fright.

What makes this kind of stunt shareable?

The setup is retellable in one line, and the payoff is emotional and human. People share it to relive the moment of courage, not to explain a complicated mechanic.

How can a brand adapt this idea without a Jumbotron?

You can swap the “big screen” for any sudden jump in visibility that feels real. For example, a live in-venue feed, a public projection, a partner-owned network of screens, or an unexpected “broadcast” to a larger nearby audience.

British Airways: #lookup points to planes

Last month, British Airways set up an interactive digital billboard in London’s Piccadilly Circus. It uses custom-built “surveillance technology” to track British Airways flights passing overhead. Here, that means identifying aircraft and matching them to British Airways flights in real time, not tracking individuals on the street.

On detecting a BA flight, the boy in the ad gets up and points to the plane. An accompanying message displays the flight number and the place it is arriving from.

In high-traffic city centres, digital out-of-home works best when it reacts to the environment rather than shouting at it.

Interactive advertisements are getting more popular with brands. In May, a Spanish organization called ANAR used lenticular printing to show different messages to kids and adults in their campaign for anti-child abuse.

How #lookup works (and what “surveillance” means here)

The magic is simple. The screen stays “normal” until the exact moment a British Airways aircraft is in view. Then the creative switches to a scene that makes you do what the boy does. You look up, spot the plane, and connect the brand to the real object above you.

“Surveillance technology” sounds heavier than what’s happening in practice. In this execution, it is reported as hardware and software used to identify aircraft and match them to British Airways flights in real time. The storytelling trigger is the aircraft, not the crowd.

Definition you can reuse: Context-aware DOOH is outdoor creative that changes based on live signals from the environment (location, time, weather, movement, or public data feeds). It works when the signal is instantly understandable and the change earns attention rather than interrupts it.

In European city-centre media buys, context-aware DOOH is one of the few formats that can earn attention without relying on volume.

Why it lands: a micro-surprise that answers a real question

Most outdoor advertising asks for attention first, and only then offers meaning. #lookup flips that order. It gives you meaning first. A child pointing at something real. Then it rewards your curiosity with an answer you cannot get from a static poster. What flight is that, and where has it come from? Because the trigger is a plane you can actually see, the data reveal feels like an answer to curiosity, not an interruption.

Extractable takeaway: If the environment makes people ask a question, your creative should answer it instantly with one human-readable data point that completes the scene.

The real question is how you turn ambient curiosity into a brand-credit moment people choose to share.

This is the rare “brand moment” where the interface and the emotion line up. A real plane prompts real curiosity. The billboard supplies the missing information. The brand gets credited for the experience.

What British Airways is really buying with this idea

At one level, it’s a smart stunt. At a deeper level, it’s a reframing of air travel. Instead of selling price, routes, or amenities, it sells the feeling of possibility and the breadth of the network.

It also turns a passive medium into an earned-media engine. When a billboard reacts to reality, people record it, talk about it, and share it because it feels like “proof,” not persuasion.

How to borrow the #lookup pattern

  • Pick a signal people already notice. Planes, trains, weather shifts, match scores, queue length, local landmarks. The trigger should be obvious without explanation.
  • Make the reaction immediate and legible. If the audience needs to read a paragraph to understand the mechanic, the moment is lost.
  • Answer a question the environment creates. “Where is that going?” is stronger than “buy now.” Build the creative around curiosity.
  • Use data as a storytelling ingredient, not a dashboard. Flight numbers and origins feel human when they complete the scene, not when they look like telemetry.
  • Keep privacy optics clean. If you must use loaded terms like “surveillance,” clarify what is being detected and what is not.

A few fast answers before you act

What makes the British Airways #lookup billboard “interactive”?

It changes its creative in real time based on a live external trigger. A British Airways aircraft passing overhead. That trigger causes the billboard to play a scene and display flight details tied to the specific plane.

Is this the same as QR codes or touchscreens in outdoor ads?

No. QR codes and touchscreens require deliberate user input. #lookup is environment-triggered interaction. The “input” is a real-world event, not a tap.

Why does real-time data improve out-of-home advertising?

Because it turns a static message into a situated experience. When the content matches what is happening around you right now, attention feels earned and the brand feels more relevant.

What’s the simplest way to replicate this pattern without complex engineering?

Use a clean, reliable signal you can access easily (time of day, weather, local transit status) and design one dramatic creative switch that is instantly visible from a distance.

What’s the biggest risk with “reactive” outdoor ads?

Overcomplication. If the trigger is rare, hard to understand, or the creative change is subtle, the concept will not land. Optimise for clarity and frequency of payoff.
