First post of 2015!
I got 3 new apps in the store for 2015 already, as you can see on my 'My Games' page
Also, I'm currently testing Unity Ads with Videos. Let's see how this will go. In fact, even if you don't need anything Unity-related, just register yourself on the Unity-Site (if you haven't already), go over to http://unityads.unity3d.com/ , login and download the framework/lib you need (iOS respectively android)
Other than that, it's just a few lines of code, and voila! you get your video ads
On the other hand: Though my app has been in the store for some time, it didn't really generate revenue :/
