Unexpected: The McDonald’s jingle was first introduced to the world in the early 00s and has lived in everyone’s head ever since. We reimagined what an audio ad could be by putting the jingle in the hands of everybody, literally. When dialing 156964544 in the right rhythm on your phone’s keypad, it sounds like the McDonald’s jingle.

We simply bought the phone number – making it possible for people to call the McDonald’s jingle – turning it into an interactive experience for all our customers to take part in. Just by dialing to the melody. Everyone who called was rewarded with a treat in our app. And one lucky caller won a golden card loaded with money to spend on any McDonald’s in Sweden. That’s how we got people to start tapping the jingle on their phones, all across the country.

Works: The campaign led to over 5000 swedes calling the number, 4 500 000 impressions (half of Sweden’s population), 43 000+ new downloads of the McDonald’s app, and 55 000 interactions across all platforms.
