British marketers are doing a nice job of responding to breaking sports news this month. We saw the Specsavers ad themed to England’s World Cup soccer loss. Now, we see this KitKat ad, which JWT London apparently whipped up within an hour of the completion of the marathon Wimbledon match between John Isner and Nicolas Mahut. See the full ad after the jump, with the payoff tagline, “Have a break. Have a KitKat.” Campaign Live reports that JWT dispatched three ad-bikes to the Wimbledon grounds the next day to amuse the tennis fans there.
