Huffington Post

The Huffington Post, the left-leaning news and opinion site, is an honest-to-goodness new media powerhouse. What began in 2005 as a group blog for conservative-turned-liberal pundit Arianna Huffington's celebrity pals now attracts more than double the traffic Matt Drudge gets in any given month. More importantly, Huffington is attracting something no media company these days has: venture capital.
