Weber Shandwick Worldwide has regained its status as the biggest PR firm following Interpublic's decision to fold BSMG Wordwide--a former True North unit--into WSW. The move creates a PR colossus with $535 million in combined fees, according to rankings compiled by the Council of PR Firms. WSW beat out Fleishman-Hillard, who reported $343 million in fees to the Council, for the number one spot.
