How to make in game ads for PC?

Hello, I want to make in game ads in my game, which should be available for all platforms. Do you know an ad provider who supports all platforms?

Unfortunately, I don’t know any ad provider that offers a SDK for desktop applications. The closest I could find are providers for Windows Store applications (AdMob, DesktopAd and Microsoft Advertising SDK). DesktopAd supports ads for OSX apps. However, the UE4 support for packaging for Windows Store is still under construction.

I suppose you could use browser UMG control or one of the plugins that offer similar functionality and serve web ads instead.

Is this possible now ? Any luck with in-game ads for PC atleast ??
