Hilton Worldwide has selected Edelman as global AOR after a six-month competitive review. The multi-million-dollar account also includes AOR for Waldorf Astoria Hotels & Resorts and Conrad Hotels & Resorts. Work will include services for Hilton HHonors, social media initiatives, and an overall “global alignment.”

Cohn & Wolfe had been the incumbent but declined to participate in the review. Ketchum recently won the business for Hilton’s DoubleTree brand.
