There's plenty of alarmism in The Hidden Persuaders—I think it's fair to say that Freudian 'depth psychology' and subliminal imaagery turned out to be less of a threat than once feared—but once you read what he says about "good guys" versus "bad men" in childrens' TV https://books.google.ie/books?id=29jhBwAAQBAJ&pg=PT76&lpg=PT... you'll never look at Scooby-Doo or the 1960s in the same way again. In that respect I think Thomas Frank's The Conquest of Cool https://www.press.uchicago.edu/ucp/books/book/chicago/C/bo36... may be something of a successor to Hidden Persuaders, but I haven't been able to read it myself yet.
