What's new about it is that as the means of creating the requsite affective environment of hyperreality ("engagement") gradually became available not only to nation-states but to private parties (down to the individual amateur influencer starting with no political agenda), they managed to interpose themselves as the very means of our critique of themselves.
Which on the meta level is a genius, as it establishes whole new channels for inter-reality exchange (a.k.a. cultural osmosis) on a first-come-first-serve basis, knowledge arbitrators love those. Not everyone necessarily finds it too comfy to find themselves in the same ecosystem as said ingroup though. Hence also the equally elaborate evolution in faux-antisystemic reaction since the turn of the century (while they try to bury the potential of technology as means of critique and bottom-up social reengineering.)
24 isn’t an example of “Manufacturing Consent” because there’s no alignment of interests of incentive structure. It’s an example of a different thing, that is an underlying cultural pattern that’s reflected both in media and foreign policy. Americans love their heroes to shove weenie bureaucrats in the locker. 24 is just Dirty Harry in a more contemporary law enforcement setting.
