If you watch this series of videos from Charlie Brooker's Screenwipe you'll learn the whole sad sordid history of TV news. He's talking about the BBC, but he could just as easily be using CBS or NBC as his examples.
In Brooker's discussion there are four eras of news, ending with the current noise machine:
- Authoritative: In the early days, the news exists to explain the world to its audience and relies on facts.
- Adversarial: With Watergate, the news exists to expose corruption in high places and relies on confrontation.
- Sympathetic: The end of the cold war catches the News by surprise. The news loses its sense of good and evil, right and wrong. It is out of touch and elitist. So it goes out in search of authentic experience. Reporters become memoirists living out gritty but staged docu-dramas to show that they understand what life is like for regular people.
- Self-Referential: The news relies solely on the opinions of the masses. Reporters become pundits and public opinion is the only valid criteria for "truth." News reportage relies on live camera reports that contain no actual information.
Here's part 1 of Screenwipe. Part 2 has the most relevant info, but it's good to watch the whole thing.
