Apple launched iAd Workshop in early June of this year. It makes in-app advertising more accessible to developers. The service allows for ad campaign budgets starting at US$50, making it easier for developers to promote their apps directly to iPhone, iPad and iPod touch owners. Shortly after iAd Workbench was launched, Apple ran into a security breach which shut the service for days. Today, the US Patent and Trademark Office published Apple's trademark filing for iAd Workbench.
