Publishers Information Bureau said April ad pages in consumer magazines dropped 1.5% from a year ago to 18,967.32 pages. For the January-to-April period, consumer magazines recorded 66,368.6 ad pages, a 3.1% decline. The declines can be tied to the two largest ad revenue categories--automotive, which was flat at $473.5 million in the first four months, and direct response, which at $294.9 million was down 11%. The No. 6 category, drugs and remedies, was up 47.8% to $214.8 million.
