B2B print advertising revenues remained below 2011 levels in July, as they have every month this year, per the latest Business Information Network report from the Association of Business Media (ABM). July’s ad sales totaled $557.5 million, down 4.5% year-over-year. That’s actually an improvement from May and June, which saw ad sales down by more than 7% and 8%, respectively. For the year-to-date, total spending has dropped by 4.1%, from roughly $4.5 billion to $4.3 billion. Still, it’s worth noting that despite falling ad sales, print still commands roughly 30% share of the total B2B media market.
