DISH has nothing. I gave up. Glued here for now.
Hey, how'd you know I have DISH? :)
Comcast cable in Atlanta has CNN International; no BBC World, but supposedly the Beeb is launching a 24-hour news channel targeting the US market, and trying to get carriage for it.
Al-Jazeera International has pushed back its launch date again and again; I don't know what their current target is. No, I don't pretend for a moment it'll be a reliable news source, but you can still glean useful information if you apply the right filters.
In the Soviet days, folks got pretty good at reading between the lines of Pravda and Izvestia and got a better idea of that was going on than you might expect. Besides which, it never hurts to hear what the Arab world is hearing; the better not to be surprised by their reactions.
When there's breaking news in the overnight hours, CNN sometimes (but not as often as it used to) gives its signal over to CNN International. I don't know why Fox doesn't do the same with its corporate cousin, Sky News. It wouldn't be as good as having their own talent on screen, but it'd be a lot better than re-runs. All I can figure is that their agreements with their video sources don't cover the US; I hope they fix that as they renew them.
I wouldn't suggest pre-empting programming across the dial, the way the media conglomerates did on 9/11/2001, but I'd like to think that with the vastness of the modern cable dial, each of the big companies (News Corp., Time Warner, Viacom) could spare at least one widely-avaiable channel for news of this magnitude.
But the trend on Fox News, CNN and MSNBC seems to be toward fewer hours of live overnight and weekend coverage. They have market research I don't, so I can only assume that it isn't cost-effective; anyone who's that interested in news at this hour has fast Internet access, I guess.
