The billboard seems to be a growing darling of marketing and this year, for the first time ever, outdoor entries at the Cannes Lions overtook the number of press submissions (5660 outdoor entries vs. 5007 press entries). And while the majority are still static and passive, some of the more progressive outdoor executions aim to inspire more interactivity, both in real life and, increasingly, online. And Saatchi & Saatchi has gone down this road, setting a manuka billboard on fire to launch Sealord’s new hot-smoked salmon.
