Damn. I played around with PiHole years ago on an original Raspberry Pi Model B, and kinda forgot about it--it broke some stuff, and most of my connected devices could run their own adblocker.
Only in the past year did I finally buy a "Smart" TV and leverage its existing GoogleTV apps, because I got tired of trying to maintain my aging Kodi Box. I should probably setup PiHole anew and point my Smart TV's DNS at it...
