iAd is a mobile advertising platform developed by Apple Inc. for its iPhone, iPod Touch, and iPad line of mobile devices allowing third-party developers to directly embed advertisements into their applications.
Similar to AdMob, iAd will facilitate integrating advertisements into applications sold on the iOS App Store. If the user taps on an iAd banner, a full-screen advertisement will appear within the application, unlike other ads that send the user into the Safari web browser. Ads are promised to be more interactive than on other advertising services, and users will able to close them at any time, returning to where they left their app.
