From comScore’s Ad Metrix:
U.S. Internet users received a record 1.1 trillion display ads during the first quarter, marking a 15-percent increase versus year ago. Total U.S. display ad spending in Q1 reached an estimated $2.7 billion, with the average cost per thousand impressions (CPM) equal to $2.48.
*Display ads include static and rich media ads; excludes video ads, house ads and very small ads (< 2,500 pixels in dimension)

The operative word relative to all the above comScore display advertising data is “Received”.
It seems to me the headline could have read “one trillion display ads delivered in Q1 2010″ but that wouldn’t have necessarily framed comScore’s position on the value of online display advertising as favorably.
