Big Journalism is staking the claim that media is now at war with one another: Big Media versus Small Media; Old Media versus New Media; Left Media vs Right Media. You get the picture.

So writes the founder of new website Big Journalism, Andrew Breitbart, primary developer on the Huffington Post and publisher of a series of online news sites.

“If the media isn’t going to take the large clues of losing subscribers, dwindling viewers, thriving alternatives – perhaps something more aggressive will instigate a change for the better,” he adds.

“Even if you’re one of those awful, biased old-media types we seek to destroy, welcome to Big Journalism, where the spirit of free inquiry lives on.”

Just a few days old the site, which has a US focus at present, says it will take on journalism, reporters and bloggers alike in a “metaphorical war” against “pure hackery and media bias”.

If it lives up to these promises, it will certainly be a media site to watch in 2010.
