KitKat 'The longest tennis match ever' by JWT London

When John Isner recently beat Nicolas Mahut 70 - 68 at Wimbledon in the longest tennis match ever, JWT London devised a tactical ad for Nestle's KitKat brand, which is all about having a break.

Within an hour, JWT London had the poster devised and ready to be sent to Wimbledon for the next day's play.

Three ad-bikes were dispatched to the gates of the Wimbledon Championships, showing the posters to thousands of appreciative fans.
