September 10, 2018 – AdWeek (USA) — COMvergence’s new report singled out the best—and worst—performing U.S. media agencies in 2018 so far.
COMvergence released its report of the best-performing media agencies through the first half of 2018, revealing Publicis Groupe’s Blue 449 as the top shop in terms of new billings due to its retention of T-Mobile’s offline account, which is estimated to be worth $940 million.
