Walter Cronkite only had to keep viewers interested for a 1 hour news show each day, not 24/7. The network his show ran on spent most of its time airing things that were not news. CNN is trying to run news 24/7, and of course it's failing to keep people interested given that. Also, Walter Cronkite had only two other major networks to compete with. CNN has to compete with however many cable channels there are plus the entire Internet. I'm not sure even Cronkite could have kept 30 million viewers in today's environment.
