Apple’s iAds began to appear in some App Store software on Thursday, bringing the dynamic, interactive in-app experiences to users on the scheduled July 1 launch date.

While iAds began to appear in some applications, not the entire iAd network has have gone live. For example, the Showtimes application from Avantar still has a placeholder banner that reads “iAd,” but no advertisement is displayed and it cannot be selected. And some applications, such as “Mirror: for iPod and iPhone,” sometimes have a blank space.

iAds provide richly interactive ad experiences inside developers’ apps, providing them a 60 percent cut of the advertising revenue. The hope is the advertisements — noted by the iAd logo in the corner — will be more compelling to users, because they don’t have to leave their app and launch a browser to view them. At least that’s what Steve Jobs would have you believe.

Early sponsors include Dove and Nissan. It is believed that companies paid $10 million in order to be among the first to advertise with the iAd service. Apple reportedly aims to charge companies close to $1 million for ads on its mobile devices this year.

The advertisements on iAd use navigation methods that iOS users are accustomed to, such as tapping or swiping across the screen, and shaking the handset itself for interactive features included in the advertisement.
