Theres not been any big issues with CNNI covering overnight US news has there? Obviously a bit wierd when US news comes from London but haven't CNN/US got bigger problems
if anything breaks in the US, looks like they are in big trouble anchor-wise (latest example - Times Square bomb).
Being an insomniac on the west coast, I have seen this in action quite a bit. CNN is better than Fox or MSNBC at keeping overnight viewers abreast of breaking news, but it's still not great.
Breaking news stories usually aren't mentioned at all from 11pm until American Morning at 6am. If the story is breaking from the US or is a reasonably large international story, then CNNI will cut in at the top of the hour and stay on for 5-15 minutes. If it is a US story, then Domestic will try to take it over if they can, either by having AC stay late (which is very rare) or starting AM early at 4am. But Domestic usually does nothing and lets CNNI handle it.
Tonight, with the boat in Israel, they've simulcasted the first 15 minutes or so of World Report from London with Don. They go back to the reruns in progress afterward. I'm not expecting much at 5am because even CNNI is in reruns then (Larry King) but I'm sure Monita will pop up for five minutes, maybe.
It's adequate, I guess, and it's better than Fox and MSNBC who hardly ever break in overnight, but it's still peanuts compared to the 24-hour news channel that they claim to be.
