LONDON: Seven campaigns have been shortlisted for the $10,000 Warc Prize for Innovation 2013, which rewards the best case study worldwide of effective innovation in communications.

The panel of 15 judges, chaired by Howard Draft, Executive Chairman of Draftfcb, praised the shortlisted entrants for their original approaches to challenges such as real-time marketing of food brands, increasing hotel revenues, selling train tickets and demobilising terrorists.

OREO, from the US, and Kissan Ketchup, from India, are the food brands represented, while V/Line, Metro Trains Melbourne and Art Series Hotels, all from Australia, are the leisure brands.

Two non-profit brands make up the seven – the Peres Center for Peace, from Israel, and the Group of Humanitarian Attention to the Demobilised, from Colombia.

McCann, with two entries, is the most-represented agency network on the shortlist. Others include BBR Saatchi & Saatchi, Draftfcb, Naked Communications, Lowe-SSP3 and Mindshare.

The winner is due to be announced on warc.com at 10.00 GMT on June 5.

In addition, Warc is also awarding a Popular Vote trophy for the entry that attains the highest combination of "likes" of its video on our free Warc Prize Vimeo page and downloads of its case study on warc.com.
