The U.S. ad market expanded 3.1% in May versus the same month in 2018, according to the latest data from Standard Media Index.
The U.S. Ad Market Tracker, a collaboration of SMI and MediaPost, slid slightly from April, falling 1.2% on a sequential basis, but May nonetheless posted the strongest index of media-buying demand for the month since SMI began tracking it in 2011.
Most of the demand appears to have come from the largest advertisers.
The top 10 product categories rose 3.4% in May vs. May 2018, while all other categories actually declined 5.6%.
