Blogs, tweets and YouTube videos give us an up-to-the-minute sense of what is happening in Iran, but to make sense of it all you need a historical perspective. That's why it is great that World Focus on PBS has been airing interviews with Ervand Abrahimian, a history professor at Baruch College of the City University of New York.
Check out his most recent appearance, and previous interviews, on the World Focus homepage.
World Focus, which combines international coverage from outfits like Deutsche Welle and Al Jazeera, blogs from around the world, and analysis from commentators in the the US, has become one of the best ways of keeping up with international news and perspectives. In an age of diminished international reporting on the US networks, it is indispensable.
