Bulmers is refreshing its advertising strategy after appointing Ogilvy & Mather to its UK ad account. The WPP agency won the business after a competitive pitch process. Ogilvy & Mather, which already handles sister Heineken brand Kronenbourg 1664, won the account from Adam & Eve/DDB. Heineken has tasked Ogilvy & Mather with pursuing a new creative direction for the cider brand.
