The total ad market appears to be stabilizing, says Bernstein’s Research, but with Q1 having been so brutal, stability isn’t feeling so good. Ad spending declined 15.1 percent — a new all-time low for Bernstein’s six-year-old ad-tracker database. No single platform saw growth in Q1, as online ad spend fell 4 percent, a first for Bernstein’s ad tracker. As for traditional advertising, this was the eighth consecutive quarter of negative growth, as it dropped 18.4 percent. See the chart below to look back at the past six years.
