Members of the American Publishers Association (OPA), and this is the largest American media with a cumulative audience of 108 million people, have agreed to try out three new advertising formats for banner advertising.
Fixed Panel (recommended width is 336 pixels, height is 860), which is organically fixed in the page layout, scrolling is needed to view the entire banner.
XXL Box (recommended width 468, height 648) - such a multimedia window with tabs, pages and the ability to run video.
Each of the sites included in the OPA association has pledged to try at least one of the three new banners no later than July 1, 2009. If the experiment is successful, then some of the formats can be approved by OPA and added to the standard ones.
