There are free TVs now that are completely subsidized by ads: https://www.telly.com/

But don't think people who can afford the more expensive TV are also more tech-savvy. Some just want a nicer TV. Also, they are a much more lucrative target market than people who cannot afford the nicer TV.

I finally saw one of these in person last year!

It was as fascinating as it was terrifying.

It had a noticable array of sensors and (I think?) microphones along with a camera smack dab in the middle. Above that was its permanent ad display. The TV also has access to its own portal, which was what was on when I saw it. An AI-generated reporter was talking about entertainment news.

Not even Orwell could've imagined a better telescreen than this. You know it's chock full of anti-defeat protections to prevent curious minds from scoring a free TV.
