iAd App Network will be Discontinued
January 15, 2016

The iAd App Network will be discontinued as of June 30, 2016. Although we are no longer accepting new apps into the network, advertising campaigns may continue to run and you can still earn advertising revenue until June 30. If you'd like to continue promoting your apps through iAd until then, you can create a campaign using iAd Workbench. We will continue to keep you updated, but if you have any questions, contact us.

According to the official announcement, new registrations for "iAd" have already ended, and the iAd service will be provided until June 30, 2016, after which it will be completely discontinued.

Well, in my case, I gave up on it early and moved to Google's AdMob.

Is this a complete withdrawal, or will the service be revived with some kind of renovation?
