In April, nearly 60% of U.S. display ad impressions were of the standard GIF/JPEG variety, according to comScore's Ad Metrix report. JPEGs accounted for most of that – 42.4% of total ad impressions vs. 14.1% for GIFs.
Flash and rich media ads combined to represent 40.3 percent of all display ads viewed.
In terms of formats, banners accounted for 23.1% of all impressions, followed closely by rectangles (22.7%) and non-standard units (22.1%).
The most common specific ad sizes were medium rectangles (300 x 250 in dimension) at 18.6%, leaderboards (728 x 90) at 18.3%, and buttons (120 x 90) at 14.7%.
Pop-ups and pop-unders now represent less than 1% of all display ad impressions, most likely a function of the pop-up blockers now standard in most browsers.
New Online Publishers Association ad formats, such as the 970 x 418 pushdown and 468 x 648 XXL box, are just beginning to gain adoption and currently account for only 0.1% of impressions.
