It’s official. The Wall Street Journal has been Fox-ified.

It took Rupert Murdoch only three and a half years to get there, starting with the moment he acquired the paper from the dysfunctional Bancroft family in December 2007, a purchase that was completed after he vowed to protect The Journal’s editorial integrity and agreed to a (toothless) board that was supposed to make sure he kept that promise.

Fat chance of that. Within five months, Murdoch had fired the editor and installed his close friend Robert Thomson, fresh from a stint Fox-ifying The Times of London. The new publisher was Leslie Hinton, former boss of the division that published Murdoch’s British newspapers, including The News of the World. (He resigned on Friday.) Soon came the changes, swift and sure: shorter articles, less depth, an increased emphasis on politics and, weirdly, sometimes surprisingly unsophisticated coverage of business.

Along with the transformation of a great paper into a mediocre one came a change that was both more subtle and more insidious. The political articles grew more and more slanted toward the Republican party line. The Journal sometimes took to using the word “Democrat” as an adjective instead of a noun, a usage favored by the right wing. In her book, “War at The Wall Street Journal,” Sarah Ellison recounts how editors inserted the phrase “assault on business” in an article about corporate taxes under President Obama. The Journal was turned into a propaganda vehicle for its owner’s conservative views. That’s half the definition of Fox-ification.

The other half is that Murdoch’s media outlets must shill for his business interests. With the News of the World scandal, The Journal has now shown itself willing to do that, too.
