Also see The Attention Merchants by Tim Wu.
Neil Postman's Amusing Ourselves to Death (1985) followed by Tim Wu's The Attention Merchants (2016).
The former is a bit more abstract and makes the case that Orwell was wrong and Huxley was right. 1984 worried about a world controlled by Big Brother with government censorship while Brave New World showed a dystopia where censorship wasn't necessary -- just take some soma and be distracted.
The latter takes a hard look at our current attention ecosystem.

I cannot recommend Tim Wu's book The Attention Merchants enough.
