Nissan, which created a multilayer interactive ad for its electric LEAF car, said customers spent an average of 90 seconds with the ad — 10 times longer than interaction times for comparable online ads. Moreover, people chose to “tap” on the Leaf iAd five times more frequently than they clicked on regular online display ads for the Leaf.

“We feel pretty strongly that this is the way to capitalize on where the mobile Web is heading,” said Chad Jacoby, a senior manager of Nissan’s media operations. “What iAd promises is the most progressive thing I’ve seen to date” in digital advertising.
