Apple and Disney have put together a special preview iAd for the iPad that should show up on the U.S. App Store today.

Featuring Disney's upcoming movie "Tron Legacy," the new iAd will not only be a way for users to learn more about the movie, but it is also the very first iAd on the iPad.

"Disney and Apple are excited to debut the 'Tron Legacy' iAd today as a special preview of iAd for iPad, which launches next year," said the two companies in a joint statement. "iAd brings Tron's pulsing energy and vivid graphic style to iPad's stunning display, creating a truly immersive ad experience."

When you tap on the ad, you will be given the ability to watch full screen videos and trailers from the film, view a photo gallery and character bios, and listen to music previews from the Daft Punk soundtrack.

The iAd will also give users the ability to download content to their iPad. You will be able to get gallery content, links to purchase the soundtrack, a mapping feature that locates the nearest theater, and e-mail integration that lets the user send an image from the movie to a friend, inviting them to see the movie.

iAd integration is not widely available on the iPad, yet. However, iAds on the iPad are expected to be available to other companies in early 2011.

Of course, it makes sense that Apple would choose to partner with Disney. In 2006, Disney bought Pixar from Steve Jobs for $7.4 billion in stock, making Apple's CEO the largest single shareholder of Disney and a member of its board of directors.
