As expected, Katie Couric didn't drastically change how the networks do the nightly news, though there were a few interesting tweaks and one major scoop.

Couric has been saying that she wants to go deeper into the news headlines, and she seems to be doing that, by having more than one guest come on during a story about the war. At the same time, there seems to be less stories covered in the half hour than there used to be. And, of course, the web is going to play a big part in the program. The broadcast is the very first to be simulcast on the web live, and Couric is keeping a blog. Well, she started it. Looks like "CBS & Co." will be contributing, which probably means that Couric won't do much at all and other staff members and reporters will do most of the blogging.
