This year’s list of nominees was marked by the increase in submissions in the digital categories, most significantly for Best Overall Digital Strategy and Best Microsite.

Longtime Custom Content Council member and former chairman Michael Winkleman received the John Caldwell Lifetime Achievement Award for his work within the industry and contribution to the association. Winkleman, who created the Pearl Awards, co-founded Leverage Media in 2001 after transitioning away from a successful editorial career that included launching Content where he served as editorial director for three years.

The international nominee list included 587 entries from 13 countries representing brands like Coca-Cola, Ford, Walmart, Whole Foods Market and Geico. A group of more than 30 judges assembled in New York, Washington D.C. and San Francisco to make final decisions on winners.
