The internet has had one major positive effect and that is that it has reduced the power of the establishment media to control the public discourse. It used to be the case that once you had achieved a position of authority in the media, you could say pretty much what you wanted and, as long as it conformed to the desired narrative of the pro-war/pro-business one party system, you could not be challenged. This enabled the discussion on important topics to be limited to within a very narrow spectrum of views, so that whatever view prevailed within that spectrum, the underlying status quo remained untouched.
It used to be the case that those informed people who read something in the paper or heard on the news that they knew was wrong had very few options, other than (say) writing a letter to the editor, which the paper had the option of refusing and which had only a marginal effect anyway.
Take for example this anecdote from Noam Chomsky’s book Understanding Power (2002) about a column George Will wrote in 1982 (thanks to Jonathan Schwarz).
[A] few years ago George Will wrote a column in Newsweek called “Mideast Truth and Falsehood,” about how peace activists are lying about the Middle East, everything they say is a lie. And in the article, there was one statement that had a vague relation to fact: he said that Sadat had refused to deal with Israel until 1977. So I wrote them a letter, the kind of letter you write to Newsweek—you know, four lines—in which I said, “Will has one statement of fact, it’s false; Sadat made a peace offer in 1971, and Israel and the United States turned it down.” Well, a couple days later I got a call from a research editor who checks facts for the Newsweek “Letters” column. She said: “We’re kind of interested in your letter, where did you get those facts?” So I told her, “Well, they’re published in Newsweek, on February 8, 1971″—which is true, because it was a big proposal, it just happened to go down the memory hole in the United States because it was the wrong story. So she looked it up and called me back, and said, “Yeah, you’re right, we found it there; okay, we’ll run your letter.” An hour later she called again and said, “Gee, I’m sorry, but we can’t run the letter.” I said, “What’s the problem?” She said, “Well, the editor mentioned it to Will and he’s having a tantrum; they decided they can’t run it.” Well, okay.
