The lead incumbents on the accounts are DDB and Carat but sources said that advertising and media networks have been approached at a holding level ahead of an imminent review.
DDB has held the global creative business since 2001 when it beat then incumbent Euro RSCG to the business.
Aegis-owned Carat last defended its account in 2007 during a review of its media business. It held onto the business following a final shootout with Group M’s MEC.
Philips called a review of its global digital business, held by Tribal DDB, eleven months ago. However, sources suggest that the review was abandoned before it reached a full pitch.
