Mercado Libre turns its logo's handshake into live Black Friday coupons — Cannes Media GP
Every handshake on Globo TV unlocks a discount: Mercado Libre turns its logo into live, personalized Black Friday coupons — the Cannes 2024 Media Grand Prix.
Mercado Libre
What it had to solve
Mercado Libre's biggest sales moment is Black Friday, when every Brazilian retailer floods TV with discount ads. To cut through the clutter, the e-commerce company wanted its TV presence to feel like a live offer rather than another ad — and to make its handshake logo, already famous across Brazil, do the work.
How it works
Black Friday is when every Brazilian retailer shouts for attention on television. Mercado Libre, with agency GUT São Paulo, chose not to shout louder: it noticed its own logo — a smiling handshake — and decided that every handshake appearing on Globo's screen could become a discount.
The mechanic was simple and live. Whenever a handshake appeared on Globo TV or its subscription channels — inside telenovelas, entertainment shows, journalism, sports broadcasts and commercial breaks — a QR code with an exclusive offer appeared on screen. AI analyzed each scene so the offer matched the moment: at the start of a football match, viewers got sportswear discounts; every program's audience profile got its own product mix.
Viewers began hunting for handshakes instead of avoiding ads, and the campaign became Mercado Libre's most successful Black Friday. At Cannes Lions 2024 it won the Media Grand Prix, with the brand describing the idea as a way to combine Globo's reach with data-driven personalization for the most important date in retail.
Why it lands
- The handshake is already the brand's logo, so the mechanic needs no new invention — only a rule.
- Coupons tied to what is on screen make the discount feel earned in the moment, not interruptive.
- Every program becomes a different ad, so one media buy covers the whole schedule with relevance.
- Viewers hunt for handshakes, turning ad avoidance into active watching.
What it did
The campaign became Mercado Libre's most successful Black Friday and won the Media Grand Prix at Cannes Lions 2024, turning the noisiest week in Brazilian advertising into a moment when viewers actively hunted for the brand's handshake on screen.
What you can take
Instead of buying more space during the noisiest shopping week, make the media moment itself the discount: turn a brand symbol into a live trigger so viewers hunt for the brand instead of skipping it.
Since then
Handshake Hunt was awarded the Media Grand Prix at Cannes Lions 2024, the festival's recognition that the idea delivered value inside the medium instead of interrupting it. Mercado Libre described the campaign as proof of its ability to innovate on retail's biggest date, combining TV Globo's mass reach with personalized, data-driven offers — and the handshake-coupon mechanic became a showcase of the company's retail media ambitions in Brazil.
