I've been reading Manufacturing Consent lately after hearing so much about it. It's very interesting through the new introduction and the first part, where the propaganda model is explained, but it drags some as the authors try to apply it to certain historical events, like the 1984 Nicaraguan Election.
Still, it's interesting, and while the model still applies to mainstream media today, the advent of the internet, smartphones, and social media's resulting displacement of mass media has lessened its effectiveness.
