Cannes Lions has long been considered a marketing and advertising festival, but as the media industry fragments and the ways brands reach audiences multiply, communicators can no longer afford to watch from the sidelines.
The core challenge for PR professionals today is keeping pace with a continuously shifting media environment. There are more channels, voices and ways to reach an audience than ever before, and understanding how to cut through requires more than instinct. It requires being on the ground, in the conversation and plugged into where the industry is heading. There's no better place to do that than Cannes.
The Programming Has Evolved
The main stage draws CMOs and executives, but the real value has shifted. The volume and quality of intimate side programming has grown significantly, and that's where the most honest conversations happen. Smaller gatherings hosted by platforms, agencies and media companies create the conditions for actual idea exchange rather than polished presentations.
Communicators are also seeing more programming built specifically for them—and from more conveners than ever. Yahoo and Axios partnered to host a communicators brunch exploring how to reinforce the storytelling principles that build trust in an AI world. Fortune hosted a communicators luncheon on the human edge in the AI era. MuckRack, Mixing Board, PRovoke Media, Page Society and others convened their own gatherings, and there were other agencies and media that hosted dinners for conversations around the role of comms today. These are rooms that simply didn't exist at Cannes just a few years ago.
Relationships Don't Build Themselves
Cannes compresses a year's worth of relationship-building into one week. Emily Sundberg, who writes the popular "Feed Me" newsletter, put it this way in an edition this week: "the warm streets of Cannes felt like LinkedIn in-person." Clients, reporters, creators—they're all there, accessible in a way that doesn't happen at a standard industry conference. A conversation on the Croisette can unlock a partnership, a story or a collaboration that would have taken months to set up otherwise. Staying plugged into what people are thinking in real time is one of the most underrated parts of the job, and Cannes delivers that at scale.
The Message Is Evolving in Real Time
Messaging doesn't exist in a vacuum. It responds to culture, technology, platform shifts and audience behavior, all of which are actively being discussed and debated at Cannes. With AI reshaping what's available to communicators specifically, so many intimate conversations organized this year addressed exactly that. Communicators who are physically present absorb the evolution of that conversation as it's happening. They see which narratives are landing, which formats are breaking through and which ideas are still looking for a home. That kind of instinct can't be downloaded after the fact.
Inspiration Is Part of the Job
PR professionals spend most of their time executing. Cannes is one of the few moments in the year dedicated to looking up. The activations, panels and unexpected moments of surprise and delight aren't just entertainment, they're a window into how brands are thinking about attention and emotion. Seeing what others are doing, and asking why it works, makes communicators better at their own craft. For example, the Grand Prix Cannes Lions award in PR went to Burson for its work on The KitKat Heist.
Being in the Room Matters
Cannes Lions is where business, culture, creators and creative collide. The most influential people in media and marketing are there, accessible in ways that don't happen anywhere else. Decisions get made, trends get set and ideas get pressure-tested in real time. Communicators who aren't on the Croisette are missing conversations that could shape their strategy, their relationships and their thinking for the year ahead.
