There's only one fast food restaurant that lets you get truly creative with their menu. Cheesy tots on chili fries, double jalapenos, a side of pickle juice. Whatever you want, you get.That restaurant is Sonic Drive-In.

So when we started working for Sonic, we let customers get creative with our brand, just like they would one of the burgers.We created a website where users chose characters, food and storylines for our commercials. They posted their creations to Facebook and Twitter, and whichever concepts garnered the most votes we developed into ads from scratch. Just like in the restaurant.
