Apple Shutting Down Quattro Wireless

Apple is planning on shutting down Quattro Wireless at the end of September to focus exclusively on its own iAd mobile advertising platform. Apple bought Quattro Wireless to get its foot into the mobile ad market, then built its own iAd platform based on Quattro’s technology.

“We believe iAd is the best mobile ad network in the world, and starting next month we’re going to focus all of our resources on the iAd advertising platform. We are no longer accepting new campaigns for the Quattro Wireless Network, and we will soon begin winding down existing campaigns,” Apple siad in a statement on the Quattro Wireless Web site. “As of September 30, we will support ads exclusively for the iAd Network.”

Apple acquired Quattro Wireless after losing out on AdMob to Google.

Since Quattro Wireless supports multiple platforms for mobile ad delivery, it’s unclear how many of its customers will stay on board with Apple’s iOS-only iAd network.
