As expected, Facebook today announced its mobile ad network, Audience Network, with three formats: banner, interstitial and native. The service brings Facebook’s existing targeting and measurement features to third-party app ad inventory.

Marketers already running News Feed ads can push them out to third-party apps through Audience Network with a single click. The service will draw on creative from existing Facebook ads. Facebook said the network is expanding to new advertisers “in the coming months.”
