No one actually knows the difference between Diet Coke and Coke Zero, but people love to have an opinion. We’ll pit Diet Coke and Coke Zero against each other in a rivalry that’ll make their differences clear — and give the public the platform they want to voice their opinions.

We’ll start the rivalry with Coke Zero vandalizing Diet Coke’s existing ads

Diet Coke will clap back on social media with a move for the ages: The tried and true hack

Which starts an all out war between the two on X

and has celebrity siblings taking sides via sponsorships

along with the el clásico rivalry of Real Madrid and FC Barcelona taking. on sponsorships for their civil war game

Diet Coke and Coke Zero begin showing up in spaces that allow people to side with their flavorite, so to speak

The ultimate flavor-off will ensue, with a 12-pack of sodas — half Diet Coke, half Coke Zero. Each can is marked with a QR code that allows the scanner to vote for their flavorite. The tally will be live broadcast on a billboard in Times Square.
