Following the recent North America Effies Awards in New York City, Warc has published 45 winning case studies showcasing great thinking and brilliant results.

Here we've chosen some of our highlights, selected because we feel they are especially interesting - either because the client faced a particularly tough challenge, such as reaching dual audiences, or because the campaign demonstrates how to implement a specific strategy, such as harnessing brand advocates.
