I’m shuddering at the thought of when it becomes impossible to be able to mute advertisements.
Delta planes with in-seat screens play ads pre-takeoff, and you can't turn them off or mute them. (Or at least you couldn't when I last tried several years ago. That customer abuse was the last time I flew Delta.)
The other day I went to get gas and was subjected to in-pump ads that I couldn't turn off or mute.
It may not be coming to our televisions soon, but it's already there in many other places.
Or, at least, this is on the medium-term todo list, and I hope I get to play with it someday. Obviously can't really commercialize the idea... :)
