Google-bought AdMob is now expanding its iPhone OS SDK to support iPad native apps. By giving developers two new ad formats—an iPad Text and Tile ad as well as an iPad Image ad—AdMob hopes to remain a viable competitor to the upcoming Apple iAd platform. AdMob’s ads will be available in 300×250, 728×90, and 468×60 pixels, and can now host interactive content much like Apple’s platform will do.

A new report out of Bloomberg is stating Apple may have been in in negotiations with AdMob about purchasing their company weeks before Google acquired them for $750 million. A purchase of AdMob—which makes their money in the mobile advertisement business—by Apple would have furthered the competition currently going on with Google, a company dominating search advertisements.
