Apple on Thursday announced a new feature for developers that will be available in iPhone OS 4 — iAds. Apple CEO Steve Jobs described iAds as a mix of emotion and interactivity, something current ad platforms don’t provide to users. Jobs said this is missing from both desktop computer advertising and mobile ads.

Apple’s iAds will deliver both. Apple said it has figured out a way to do interactive and video content with iAds. What’s more, it will not take you out of the app, like current ad systems do.

Jobs said that the average user spends 30 minutes a day using apps. If Apple put up an ad every 3 minutes, that’s 10 ads per device, per day or 1 billion ads a day.

Apple will give developers 60 percent of the ad revenue, while it keeps 40 percent for itself. Apple will sell the ads and host them for developers.
