The problem. The idea. The experience.
Taco Bell had campaigned for a taco emoji. The creative opportunity was to celebrate its arrival through participation rather than another announcement. This record covers the emoji-engine activation, with the petition treated as background rather than a separately counted case.
How the idea came to life
People tweeted a taco emoji and another emoji to the brand and received a custom visual response. The One Show describes a prepared library of 1,294 responses. The system recombined a familiar food symbol with an individually chosen cue.
How it reached people
A sponsored trade report dated 10 November 2015 documents the newly launched Twitter activity and an initial library of 600 pieces. The later award entry records a larger library; these are different source snapshots, not interchangeable totals or numbers of participants.

Read the data in context.
The numbers below describe different kinds of outcomes. Their date, scope and reporting source are part of the result.
The award archive verifies a 2016 Merit, not a Pencil. Neither opened source provides independently verified incremental sales, unique participants or retention. The existence of many responses demonstrates production scope, not customer growth.
The creative mechanism.
Two familiar inputs generate a surprising branded response
Make the first action obvious
Participation begins before the payoff. A person should understand the input without reading a long instruction thread or granting broad account access. In an adaptation, show one complete example and make the boundaries visible. If people need staff assistance to discover the rule, improve the invitation before expanding the content library.
Use surprise within a coherent rule
Random output can create novelty without creating recognition. Keep one element consistently connected to the product and let the other element introduce variation. Test whether people can describe the relationship afterward. The relevant design question is not how many outputs exist, but whether each feels intentionally connected to the input.
Budget for the response system
A playful front end conceals illustration, testing, moderation and platform dependencies. Start with a small set of combinations that can all be checked. Include a polite unsupported-input response and an accessible text alternative. A larger library is useful only if quality and delivery remain predictable when attention arrives.
Measure voluntary return separately
Someone may try a generator repeatedly without becoming more likely to buy. Distinguish unique users, repeated attempts, shared outputs and product visits. Ask a small sample whether the brand association remained clear. Compare with a simpler static invitation before concluding that automation contributed value beyond curiosity.
The intended behavior loop
- 01Notice the distinctive invitation
- 02Understand the brand connection
- 03Choose whether to engage
- 04Recall or discuss the experience
Growth job: Turn cultural relevance → into voluntary interaction → into memorable brand association. 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
Create an understandable input-and-reward rule with a small, high-quality response library.
Keep these boundaries
Do not copy the original illustrations, imply ownership of a public emoji or collect unnecessary account data.
Turn the lesson into a test.
Illustrative adaptation, not a historical campaign fact
A small-team experiment
A local art shop lets visitors combine two printed creative prompts to receive an original project suggestion.
Build the test
- Prepare twelve checked combinations using original text and drawings.
- Let adults choose anonymously and provide a readable plain-text version.
- Offer the same project materials without requiring participation.
Measure the right thing
Track completed interactions, useful suggestions, optional return visits and staff time separately.
Know when to stop
Stop if outputs become inappropriate, confusing or more burdensome than useful.
How this reading fits your brief
Start with the useful part.
Best for: Turn cultural relevance → into voluntary interaction → into memorable brand association
What to adapt: Create an understandable input-and-reward rule with a small, high-quality response library.
Prerequisites: Original creative development; Rights and accessibility review; A clear measurement plan.
Smaller-team route: A local art shop lets visitors combine two printed creative prompts to receive an original project suggestion. Constraint: Do not copy the original illustrations, imply ownership of a public emoji or collect unnecessary account data.
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 is the smallest input that gives people genuine agency?
- Does each response strengthen the product association?
