The Huffington Post

The leading advocate of a new citizen journalism model is Arianna Huffington who founded what is regarded by many as one of the most influential media organisations, online or offline, in America today.

The Huffington Post was founded in 2005 and is already one of the biggest individual news organisations in the US. It has 2,000 contributors, paid and unpaid and while avowedly liberal she says that "we are never going to cover up for anyone however much we love them."

As the Post moves into local reporting, Arianna Huffington looks set to be to Journalism in the early part of the 21st century what Rupert Murdoch was to the latter part of the 20th century.

Except a hell of a lot more liberal.

You can read a review here of a talk the Arianna gave at The Guardian's "Future of Journalism" conference last year, or you can listen to a six minute excerpt here.
