Apple

This year, Apple head Steve Jobs announced the company would branch out into mobile advertising.
The iAd system allows developers to include advertising within their appsforthe first time.
Most mobileads kick you out of an application when you click on them, which can be annoying, but iAd keeps users in the app, and even lets you buy things through the ad.
Apple estimates that the average iPhone usercould see 10 ads per day.
iAds use HTML5, the new standard for presenting content on the web.
It allows for design flexibility through animation techniques like 3D rendering.
