You mean THIS TCL? https://ads.tcl.com/

Or THIS Hisense? https://nexxen.com/acr-data/

They all use Automatic Content Recognition (ACR) and collect profiling data to feed into an Ad service offering.

Samsung started this and is now a leading supplier for targeted advertising on TVs (because old serialized TV doesn't have such an option), this is forcing all the brands to follow and do the same, because:

#A: it creates a revenue stream based on active devices (like Apple/Google has), not just at the time of sales, and

#B: their business partners now demand it (big electronics chains won't sell a TV which will affect their targeted ad promotions)

It would be much more valuable to have proper journalists (sorry) to write an investigative report on this whole Ad-targeting industry, to create pressure not just on some TV-vendors but on all home appliances (including cable-company set-top-boxes, which do exactly the same btw).

The only way out of this is to increase public pressure to the point that a regulation (a LAW!) is drafted and enforced.
