Apple has announced a number of new advertising formats for its iOS mobile operating system as part of the iAd platform.

The two new ads, a full-screen interstitial banner and a pre-roll video, have been developed by Apple to bring in more revenue as they take up an entire screen when a mobile app is in use.

Full-screen interstitial banners set out to mimic regular content pages and act as a transitional screen between two sections of an app. Pre-roll ads come in 16:9 or 4:3 aspect ratios and require iOS 7 or above.

60-second video ads

Compared to other ad platforms that already run similar products, iAd has generally been less obtrusive from a consumer perspective. Now though, Apple has decided to offer 15, 30 and 60-second variants of its pre-roll product.

Like all other iAd hoardings, marketers can use iAd Workbench to help promote apps. It is also possible to track downloads resulting from iAd Workbench by inserting an iAd App Attribution code.

Apple is set to roll out its iAd service across Russia and Switzerland, which means developers will be able to promote apps across 16 countries in total.
