The Sunlight Foundation and the Media Standards Trust launched yesterday Churnalism US which is “a new web tool and browser extension that allows anyone to compare the news you read against existing content to uncover possible instances of plagiarism” (churned from their blog post).

“Churnalism’ is a news article that is published as journalism, but is essentially a press release without much added. In his landmark book, Flat Earth NewsNick Davies wrote how ‘churnalism’ is produced by:

“Journalists who are no longer gathering news but are reduced instead to passive processors of whatever material comes their way, churning out stories, whether real event or PR artifice, important or trivial, true or false” (p.59).

Kaitlin Devine, another developer on Churnalism, provides a two minute tutorial on how Churnalism US works:
