Many people think they know the taste of Coke Zero, but they actually don't. So Ogilvy & Mather created a campaign for Coke Zero that viewers could literally drink, irrespective of whether it was on a billboard, tv, print, or radio.
By simply "Shazaming" the ads, viewers could see Coke Zero pouring in on the screen of their smartphones, filling a glass, which then ended up into an actual free Coke Zero coupon that could be redeemed at select retail stores across the US.
Thirsty? Drink the ad yourself...
In 2011, Switzerland's Graubünden Tourism and agency Jung von Matt created a clever stunt to publicize the remote mountain village of Obermutten on Facebook.
Then in 2015, they decided to target people a little closer to home i.e. the stressed urban commuters in a Zurich train station. This time they used an interactive display featuring a genuine Graubünden mountain man who could see and talk to those who walk past. Passersby who interacted with the mountain man were offered an all expense paid trip to Vrin, a mountain village in the Lumnezia Valley. The only catch being, that they needed to drop everything and jump onto the train leaving from the next platform.
To promote the Quebec City Magic Festival, agency lg2 created a poster that featured a magicians hat. The message on it was however hidden from the naked eye with the help of an invisilble ink. Curious passersby who took pictures of the poster using their cell phone (flash on) unlocked the message. A lucky few even got a free ticket for the festival's closing show.
With the start of the flu season, Theraflu in Poland wanted to create a tool that enabled passersby to check if they have a fever without actually interrupting their daily commute.
So Saatchi & Saatchi developed the world’s first outdoor ad with a live thermo-scanner camera, which could check the body temperature of the person standing next to it in real time.
The thermo-ad also enabled users to take a thermo-selife (which they could download from a microsite or via a QR code) and share it on social media using the hashtag #TherafluThermoscanner or send it by email to their boss to explain their absence.
