Nobody really knows the difference between Diet Coke and Coke Zero; both are zero calorie, zero sugar — yet somehow not the same. We’ll set up a playful rivalry that makes their differences feel real — and worth defending.
From bold takes to everyday preferences, we’ll give people the platform they’ve been waiting for to choose their favorite and back it loudly.
So the only question left is:
We’ll start the rivalry with Coke Zero vandalizing Diet Coke’s existing ads.
Continuing the feud, Coke Zero’s social accounts are briefly “hacked” by Diet Coke, sparking playful confusion and chaotic reactions across followers.
