Creativity 50 2010: Jeff Benjamin, Andrew Keller and Rob Reilly

While this trio of executive creative directors has effectively been running Crispin Porter & Bogusky's creative department for several years, the elevation of Alex Bogusky to chief creative insurgent at parent MDC Partners makes it clearer that the torch has been passed. And under their leadership Crispin Porter has embraced digital media—and deployed it in creative and effective ways—like few others.

Mr. Reilly said a key moment in that transformation was when Mr. Benjamin's title shifted from executive creative director-interactive to just executive creative director, symbolically marking the full integration of digital into the agency's core.

The proof is in the work: Burger King's Whopper Sacrifice saw more than 234,000 Facebook friends traded in for Whoppers, and Best Buy's Twelpforce proved a powerful convergence of social media and customer service.

Said Mr. Keller: "Certain brands are expected to innovate, and some aren't. It's invigorating when you can do something great or innovative for someone who isn't expected to do that. I think you're going to see us getting more packaged goods and traditionally harder clients."
