When large format becomes a conversation

A few days ago, a striking red display on Madrid’s Gran Vía achieved something few campaigns manage: it made people stop, take out their phones, and ask out loud what was going on.

No logo. No product. Just a color and a message: “Watch out for red.”

It was Nestea.

Large format never stops surprising

At a time when everyone is talking about social media, algorithms, and digital content, outdoor advertising remains one of the most powerful media channels out there. It shouldn’t be overlooked.

A large-format billboard doesn’t appear in a feed you can scroll through. It’s not an ad you can skip. It’s there, right in the middle of the city. When executed well, it can become a phenomenon that goes far beyond the square meters it occupies.

Nestea’s campaign is a perfect example of this. The brand used a billboard as the trigger for a teaser strategy: no explanations, no context—just a color that sparked curiosity. Social media did the rest. People photographed the billboard, shared it, speculated. A physical piece turned into digital content organically.

That’s strategy!
