I’d often like to see live news on my iPad, but sources are rare. Here are the ones I’ve found:

• The CNN App for iPad has a “Live Video” feed. This has been a useful source for live news during the news from Japan.
• NASA TV for iPhone shows live streaming of NASA TV.

I’m most interested in coverage of current events, in English, that I can watch from within the US. If you can recommend other options, please post them below.
