In-app advertising

Definition
In-app advertising is advertising that appears within an app.

Overview
"In-app advertising typically involves a relationship between the app developer and an ad network, where the ad network pays the developer to incorporate the ad network’s code into the developer’s application. When the app is running, the ad software allows the ad network to send ads to the user’s device. Depending on how the ad network software is configured, the ad network may collect information from the user to provide targeted ads."
