A report outlining advertisers' plans for Apple's new iAd program indicates that the new interactive ads won't reach iPad users until iOS 4 becomes available for it in November.

iAds will go live on iOS apps for the iPhone and iPod touch starting July 1, although Advertising Age reported that "a check-in with declared iAd advertisers found that many are still in the early stages of flushing out concepts and creative."

The story added that "some are weeks -- perhaps months -- away from having an iAd in the system." It cited "an agency exec with several iAds in the works," as saying, "most advertisers won't be there on July 1; there just isn't enough time," an issue partly blamed on Apple itself.

Apple is doing "all the technical production of iAds, and telling agencies it will take six to eight weeks to produce an ad after the creative is produced," the report stated.

The July 1 opening of iAd is a date selected by Apple, and "doesn't necessarily coincide with the objectives of the marketers themselves," the report said. Getting ad placements on iPad, "the device considered most promising for advertisers," won't happen until November.

Apple previously stated that a special build of iOS 4 would be released for iPad users later in the year, bringing support not just for iAd but also other features of the new operating system, from multitasking and related background services to Home page Folders and a variety of new APIs used by developers.

Some of the features introduced by iOS 4 on the iPhone and iPod touch are already supported in iOS 3.2 used by iPad, including support for spell correction and Bluetooth keyboards.
