[TABLE] Ad source

Dimension Publisher Ad source The source network that served an ad. Typical sources include 'AdMob Network', 'Meta Audience Network', and 'Mediated house ads'. When you integrate with Google Ad Manager, this dimension represents the Google Ad Manager Network name (for example, 'Bloomberg L.P. (Google Ad Manager Network 5262)'. This dimension is populated automatically when you integrate with AdMob or Google Ad Manager. If you integrate with MoPub, ironSource, or another ad monetization platform for mobile apps, you need to send the ad_impression event to populate the dimension.
