$346,775,480
The world’s largest independent public relations firm, Edelman specializes in managing the reputations of clients with image problems, including the American Legislative Exchange Council. To polish Wal-Mart’s reputation in 2006, the agency created the fake grass roots organization “Working Families for Wal-Mart,” for which a couple drove across the country blogging positive accounts of the retail giant’s employees and customers. More recently, Edelman came under fire after leaked documents revealed the firm’s aggressive plans to attack opponents of a pipeline being developed by TransCanada Corp. Within days of the leak, TransCanada announced that it was severing ties with the PR giant.
