I wouldn’t be surprised if the next iteration of TVs will take ads over a data signal over OTA deals with TV stations and display localized ads in programming and in their apps.
It's possible but it would be one way in most locations. But yeah I'm sure it'll be possible. I have it on my list to look for ways to block Amazon sidewalk by the way.
Personally I don't even have cable TV. I never watch live TV anymore. I get all my news from the web (I never liked watching TV for it) and shows I just download or stream.
