The problem. The idea. The experience.
NHS Blood and Transplant needed to recruit new blood donors. The communication challenge was to make an ongoing need noticeable without asking audiences to understand a large amount of medical information before engaging.
How the idea came to life
Participating organizations removed the letters A, B and O from names, signs and social branding. The missing characters referred to blood groups, creating a visible absence and a common action that many partners could perform without producing entirely different campaigns.
How it reached people
NHSBT dates the first campaign to 2015 in England and North Wales. A 2016 follow-up involved blood services across multiple countries. This brief keeps those editions together while identifying which reporting period each result belongs to.

Read the data in context.
The numbers below describe different kinds of outcomes. Their date, scope and reporting source are part of the result.
NHSBT reports 23,864 new registrations in England during 16–29 August 2016, compared with 12,007 in the preceding comparison fortnight. These are registrations, not completed donations or lives saved, and the before-and-after comparison does not isolate campaign causality.
The creative mechanism.
Removing a small, meaningful part of familiar branding makes an otherwise invisible shortage discussable.
Make the absent thing visible
People often notice a gap more quickly than an additional message. The useful technique is to remove a recognizable element that has a clear relationship to the issue, then explain the connection promptly. Do not remove essential instructions, safety information or accessible navigation. The disruption should create a moment of understanding rather than make a service harder for its intended users to use.
Create a partner action with low production friction
A shared rule lets organizations participate while retaining their own identity. Write the rule precisely, supply an example and identify where it should not be used. A small coalition can coordinate a reversible visual treatment across a few owned channels. Partner participation is a distribution input, however, not an outcome; count what audiences do after the treatment attracts their attention.
Preserve the distinction between interest and completion
A registration is an important step but is not the same as attendance, eligibility or a completed service. Map the entire pathway before choosing success metrics. Record each stage separately and look for avoidable drop-off. For a health-related service, leave eligibility and clinical questions to the responsible provider, and never pressure people to disclose why they cannot participate.
Match demand to the service’s capacity
A successful awareness moment can create a frustrating experience if the destination is unavailable or confusing. Confirm capacity, geographic availability and the next practical step before launch. Explain alternatives for people who cannot use the service or do not qualify. An honest waiting list or a future information option is preferable to a large burst of sign-ups that cannot be supported.
The intended behavior loop
- 01Encounter the creative
- 02Understand the specific issue
- 03Explore the supporting explanation
- 04Choose an appropriate voluntary action
Growth job: Awareness → Recruitment → Partner activation. This is an interpretation of the mechanism, not an audited attribution model.
A direction to take into the room.
Original editorial interpretation and proposed adaptation. This is a proposed adaptation, not historical campaign execution or a forecast.
The transferable principle
Give partners one reversible visual rule that points to a real service, then measure progress through its actual participation pathway.
Keep these boundaries
Do not remove safety-critical text, collect health data in a marketing form or count registrations as donations or medical outcomes.
Turn the lesson into a test.
Illustrative adaptation, not a historical campaign fact
A small-team experiment
A community repair day temporarily removes an illustrated missing piece from consenting partners’ promotional graphics to invite bookings for a verified service.
Build the test
- Choose one clearly explained symbol and retain the full organization name in accessible text and essential wayfinding.
- Confirm volunteer capacity and appointment availability before partners publish; offer a plainly labeled information page for unsupported repairs.
- Run the treatment for one week on owned promotional channels, with an easy rollback and a conventional announcement as a comparison.
Measure the right thing
Track page understanding, booking requests, appointments attended and completed repairs separately; note waiting time and unsuitable requests.
Know when to stop
Stop if people mistake the altered graphics for a closure, cannot find essential information or demand exceeds the service’s safe capacity.
How this reading fits your brief
Start with the useful part.
Best for: Awareness → Recruitment → Partner activation
What to adapt: Give partners one reversible visual rule that points to a real service, then measure progress through its actual participation pathway.
Prerequisites: Original concept and verified factual claims; Informed participant consent, rights and accessibility review; A defined comparison and outcome measure.
Smaller-team route: A community repair day temporarily removes an illustrated missing piece from consenting partners’ promotional graphics to invite bookings for a verified service. Constraint: Do not remove safety-critical text, collect health data in a marketing form or count registrations as donations or medical outcomes.
Budget: Not established by the cited sources. No cost-fit claim is made.
Trade-offs and evidence: Read the limits below before choosing a test. There is no guaranteed reach, sales lift or ROAS.
Questions for your next brief
- What does the audience need to understand before the requested action is useful?
