"Ask HN: How do you prevent ad-injection in my brain implant?"

Black Mirror episode: https://en.wikipedia.org/wiki/Common_People_(Black_Mirror)

Good to see that there's new episodes and they've still got their mojo - putting it on my list.

The National Lampoon did it in the early 70's.

IIRC Asimov included this in Foundation; the poor couldn’t afford good adblockers for the implants they’d bought (in the hope of getting a better job)
