The PR world continues to make its presence felt at Cannes, albeit perhaps not in the way intended by the festival's organisers. According to PR Lions jury chairman Dave Senay, award entries from PR firms are up by just 50 this year compared to 2010 - although hopefully there will be more winners from PR agencies this year than from their brethren in adland. Otherwise, the festival - and particularly its seminar programme - should be of considerable interest to the PR world, given the continued integration between marketing and PR - a trend that we have to tried to document in detail at the Holmes Report. A handful of PR agencies appear awake to the opportunities on offer. MSLGroup has produced a nice Cannes Centrale conversation site and iPhone app, complete with a roving reporter in the shape of American blogger Tim Seidell. Another smart move is Ketchum's decision to sponsor the Young Marketers competition. For the the third consecutive year, Hill & Knowlton is running a seminar, this time in conjunction with Angry Birds creator Peter Vesterbacka. And GolinHarris CEO Fred Cook and European co-MD Matt Neale will bravely attempt to lure people away from Black Eyed Peas frontman's session, to their workshop focused on brand authenticity. Quite sensibly, Fleishman-Hillard is running a session on 'social mobile marketing' bringing together a diverse panel that features Orin Levine from Johns Hopkins, and Mitch Spolan from LivingSocial. For our part, we will be reporting daily from Cannes, and running some online conversation analysis courtesy of Porter-Novelli. Drop us a line if you would like to meet.
