Apple’s North American iAd Network debuted July 1st and some of the major ads have already begun to roll out on iOS 4 devices. Aside from going head-to-head with Googles Admob ad platform, iAds is supposed to redefine how users experience and interact with advertising on your iPhone. One of the first and most notable iAd campaigns to appear is Nissan’s 100% electric car, the LEAF. Take a look at the Nissan iAd demo and see just how far ads have come in comparison to the static mobile ads of old. If all future iAds are even half as good as this, end users will probably not mind spending a minute or two checking out the latest interactive ads.
