Short answer
In-app advertising refers to ads served inside mobile or connected TV apps rather than on websites. Common formats include banners, interstitials, native units, and rewarded video. It is a major revenue source for free apps, and is typically measured through software development kits and mobile measurement partners rather than browser cookies.
