A phone directory brand sells a real chocolate bar, and the public lines up to buy it. That is the core twist behind Yellow Pages New Zealand’s “Yellow Chocolate”.
When a “job to be done” becomes a product on a shelf
The premise is simple and weird enough to travel. A regular New Zealander, Josh Winger, is tasked with creating, marketing, and distributing a chocolate bar that “tastes like the colour yellow”, using only businesses he can source via Yellow Pages across print, online, and mobile.
Here, a “job to be done” means the practical outcome people need help achieving, not the channel they use to achieve it.
The campaign is described as starting with a call for entries and then turning Josh’s progress into episodic content that pulls people into the build, not just the reveal.
How it works as an integrated proof, not a stunt
The mechanism is a live product demonstration disguised as entertainment. The brand does not claim usefulness. It forces a public, time-boxed build where every dependency is a Yellow Pages lookup, and the finished output is a retail product that carries the proof story with it.
That works because a public build turns a vague claim of usefulness into a visible chain of evidence people can watch, judge, and later buy.
At Cannes Lions 2010, the work is listed as winning a Gold Lion in Media, a Silver Lion in Titanium and Integrated, and a Bronze Lion in Cyber.
In mature categories where a brand needs to prove relevance to a search-first audience, turning the proof into something people can buy and share compresses “brand promise” into observable behavior.
Why “taste like yellow” sticks
An abstract brief invites participation. People argue about what “yellow” should taste like, contribute ideas, and then follow the build to see whose intuition survives contact with manufacturing, packaging, distribution, and retail reality.
Extractable takeaway: If your product is a utility people underestimate, stage a public build where your tool is the only allowed method. Then ship a tangible artifact that carries the proof narrative into everyday life.
What Yellow Pages is really buying
This is repositioning by demonstration. The chocolate bar is a carrier for a bigger reset: Yellow Pages is not an “old book your parents used”. It is framed as a modern system that can still help anyone get a job done, end to end, under real constraints.
The real question is whether a legacy utility can make usefulness feel current again without leaning on nostalgia or category habit.
What the results are described as
Results are reported as unusually strong for something that is, technically, a piece of marketing communications. The bar sold for $2. Some supermarkets reportedly sold out on launch day, and some bars were later traded online for up to $320. The campaign is described as building an online audience of more than 80,000, including around 16,000 Facebook fans and about 800 Twitter followers.
What to steal for your next “prove it” campaign
- Make the constraint the headline. “Only use businesses found via X” is clearer than any brand manifesto.
- Design for contribution. Pick a problem the audience can argue about in public, then let them feed the build.
- Ship an artifact. A real product, sample, tool, or output beats a landing page when you need belief, not awareness.
- Carry the proof inside the thing. Packaging and POS that explain “how it was made” extends the story past the content moment.
A few fast answers before you act
What is the Yellow Pages “Yellow Chocolate” campaign?
It is an integrated campaign where Yellow Pages challenges a participant to create and launch a chocolate bar that “tastes like yellow” using only Yellow Pages listings to source everything needed. The finished bar becomes the proof artifact.
Why does a physical chocolate bar matter here?
Because it turns an abstract brand claim into observable reality. People can buy the output, and the story of how it was made becomes a portable demonstration of the directory’s usefulness.
Which Cannes Lions awards is it listed as winning?
Cannes Lions listings for 2010 show the work winning a Gold Lion in Media, a Silver Lion in Titanium and Integrated, and a Bronze Lion in Cyber.
What outcomes are reported?
Reported outcomes include rapid sell-outs in some supermarkets, bars traded online for high prices, and sizeable social followings. Some recall and usage-lift figures are also reported, but vary by secondary retellings.
What is the transferable principle?
When you need to change perception of a legacy utility, do not argue. Force a public build where your tool is the only allowed method, then ship the proof as a tangible artifact.
