Since their introduction in 2011, the Creative Effectiveness Lions have become one of the most closely-watched categories at the Cannes Lions International Festival of Creativity. These Lions are awarded to campaigns for their business performance as well as their creative excellence, and WARC's own data suggest that the category as a whole has become the best-regarded marketing effectiveness award in the world.

WARC has published the full set of Lions entries and winners since the Creative Effectiveness Lions were first launched: subscribers can access the full set of this year's winners here. And we have also released a report highlighting trends among the winning campaigns, including campaign budgets, media mix, campaign duration, creative approaches, metrics and regional variations.
