Brief
Coca-Cola has held a sign at Piccadilly Circus since 1955. Today it’s the Piccadilly Lights: a single 783.5m² curved screen, the largest advertising display in Europe, shared by six brands in a rotating patchwork. Christmas there is Coke’s most public moment of the year. I was brought into RCP as interim Head of Digital Production during a high-pressure, multi-client cycle to land the Christmas Patchwork campaign on it. The original plan was interactive and app-led.
What We Built
I took over production partway through and made the call to drop the interactive app for something built to be watched, designed around how the screen actually works: brands rotate positions every 90 seconds, and each takes a 40-second full takeover every 10 minutes.
The reasoning was simple. On a site this public, with a Christmas date that can’t move, an interactive layer that fails, fails in front of the whole West End. Content made for the screen’s own format was the version that would definitely run, and definitely land.
Outcome
Delivered live on Piccadilly Circus on the Christmas date, with no second take available. The lesson is one I still apply to everything DEPARTMNT builds: interaction only earns its place when it cannot fail. When it can, the room is better served by something it can simply watch.
