eBay announced it would begin displaying new graphical advertising banners as part of its partnership with Yahoo announced in May (http://auctionbytes.com/cab/abn/y06/m05/i25/s03). Yahoo ads first began appearing on eBay in July (http://auctionbytes.com/cab/abn/y06/m07/i19/s01). Changes coming this month include the following:

• On the Motors Home Page, a new graphical ad will be appearing on the right side of the page.
• On eBay.com Search Results Pages, the size of the graphical banner at the top of the page will be increased from 468 x 60 to 728 x 90. The new size will replace the existing smaller banner as well as two small text ad placements. This new ad size is the same size as the current banner ad that runs on the top of eBay Motors Search Results pages.
• On Search Results Pages, the size of the graphical banner on the lower left navigation of the page will change to 180 x 150.
