About Channel 18
Apps are typically not used for creating awareness of other apps unless that app is owned by the same company. However, In-App ads served by Google are widely used. For example, I use the Tides app to learn when the tide is going in or out when planning my day’s sail. I have the free version, which means that I see ads when I use the app. Below is an example. A full-screen ad is showing me a local plumber. When I close it to view the app, there is a small ad at the bottom of the screen. Both are served by Google from both of these business’ AdSense accounts.
