This Windows tool makes it super easy to debloat and cut down ads on your Android TV
(www.androidauthority.com)
This is a most excellent place for technology news and articles.
(On the shield 2019) If you block this domain with your dns ad blocker, the default launcher will only show ads for the YouTube, Google TV, and Google Play Store apps (not individual shows). I find these to be far less annoying as they use muted tones.

If you have already setup your device and currently see ads, you need to reset the android tv home application data to get rid of them. This will temporarily show you the old dashboard, but the new one will load eventually (without ads).
I don't get why someone would be willing to put in the effort to block that domain rather than just install a different launcher. Much simpler, less likely to inadvertently break something else.
For me it was much simpler to just add it as a line in the field in my router settings than trying to find a launcher that was better while looking decent.
I also like the look of the launcher minus the ads as well, so that might play into it.
I'm not worried about it breaking any features tied to the ads, and I haven't had any problems in like 2 years I've used it.
