Interesting idea. Perhaps we are already living in a version of BNW, with media and constant advertisements serving the role of sleep-learning.

Yes, that is one premise of BNW, constant engagement and thus constant and immediate satisfaction is one purpose of the media, but media as a form of propaganda is an age-old tactic.

The widespread reach of modern media just makes it easier to spread any given point of view, with the chance going to the highest/most powerful bidder.

Would say that the filter bubble is probably as significant, if not more so, than ads (which have been around a long time).
