In an action called Occupy Wall Street, thousands of activists took to the streets of Lower Manhattan on September 17. The protests are continuing, with demonstrators camped out on the Financial District's Liberty Street in support of U.S. democratization and against corporate domination of politics.
But you wouldn't know much about any of this from the corporate media--outlets that seem much more interested in protests of the Tea Party variety.
The anti-corporate protests have been lightly covered in the hometown New York Times: One piece (9/18/11) largely about how the police blocked access to Wall Street, and one photo (9/22/11) with the caption "Wall Street Protest Whirls On."
The protests have been treated with brief mentions on CNN, like this one from host Wolf Blitzer (9/19/11): "Protests here in New York on Wall Street entering a third day. Should New Yorkers be worried at all about what's going on?"
