McDonald’s Save the Sundae Cone campaign had a McDonald’s Sundae Cone on the digital billboard, which was slowly melting in the heat of the city. To “save” the sundae cone, the audience needed to spin a giant fan that would ‘cool’ the sundae cone and ‘un-melt’ it. They did this by spinning a mini-fan, which was accessed through their mobile device’s web browser. At the end, participants were given a voucher on their smartphone to be redeemed at a McDonald’s across the street for a free sundae cone. The realtime network needed to be able to handle hundreds of users simultaneously, and with such a large audience, 100% uptime was vital for the campaign.
PubNub was a key infrastructure component in the Save the Sundae campaign and was used in a variety of different use cases. The reliable and low latency realtime data streaming that PubNub offers was essential for the project as a whole. With a tight realtime loop, participants, the app, and the digital billboard were all updated in realtime to mimic real life interaction.
