NEW YORK (AdAge.com) -- The Interactive Advertising Bureau today announced it has formally adopted the Universal Ad Package, a suite of four online ad sizes designed to make it easier for advertisers and publishers to plan and buy interactive media.
The move follows the IAB's recommendations,
made last December, that the industry use the following large ad units: 728 x 90 pixel "leader board," which runs across the top of a page like a giant banner; the 160 x 600 pixel skyscraper that runs vertically on the side of a page; and the 300 x 250 pixel and 180 x 150 pixel rectangular formats.
Web sites offering ad sizes in the Universal Ad Package can be identified with a new "UAP Compliance Seal." The American Association of Advertising Agencies has endorsed the formats.
Publishers planning to be compliant within the next year to 18 months include: AOL Time Warner's America Online, CNET Networks, Conde Nast Publication's CondeNet, Forbes.com, iVillage, Microsoft Corp.'s MSN and Yahoo!
