MIAMI—Nine of the world’s top 10 public relations firms and 11 of the top 13 are partnering with The Holmes Report on the fifth annual Global Public Relations Summit, which will take place in Miami this October.

The event—which has attracted more than 400 industry leaders from more the 35 countries around the world in each of the past four years—is being rebranded as PRovoke16, building on feedback spotlighting the provocative and challenging nature of the event content as one factor that sets it apart from other industry conferences.

“From the outset, we wanted to make the Global Summit a forum for challenging the conventional wisdom,” says Paul Holmes, founder of The Holmes Group. “We wanted something that stood out from industry events that feature PR people talking to other PR people about the issues we talk about every day. We sought to bring in outsiders—executives from other disciplines, authors, academics—who could provoke and precipitate new debates.”

Partners for the 2016 edition include top 15 firms Edelman, Weber Shandwick, FleishmanHillard, Ketchum, Burson-Marsteller, MSLGroup, Hill+Knowlton Strategies,Ogilvy PR, Golin, Havas PR, and Cohn & Wolfe. They include PR agencies owned by each of the big five industry holding groups.

Other partners include a host of international leaders including Adfactors (India); Atrevia and Llorente & Cuenca (Spain and Latin America); Finn Partners, Global Strategy Group, M Booth (US); Strategic Public Relations Group (Hong Kong); and international agency WE Communications.

The Independent PR Firm Forum, an event for PR agency founders and principals that precedes the Summit proper, will once again be sponsored by thenetworkone and Davis & Gilbert.

PRovoke16: The 2016 Global PR Summit, will take place at the St Regis Bal Harbour in Miami once again on October 25 and 26, with the Independent PR Firm Forum on October 24. Tickets for both events—and the Global SABRE Awards dinner on the evening of October 26—are on sale now, including a generous earlybird discount until July 4.
