According to The New York Times, in the last few months, Rupert Murdoch has moved into an office at Dow Jones & Company, publisher of The Wall Street Journal. He has pushed the paper's editors for shorter articles and more hard news. He has personally wooed reporters he wants to keep out of his competitors' hands. And last week, he oversaw the replacement of top executives, including The Journal's publisher, with his own lieutenants. And he hasn't even bought the company yet. After Thursday, when the takeover becomes official, the real changes will begin, including eliminating the Marketplace section, buying out two or three dozen newsroom employees to make room for News Corp. picks, and a decision about whether to make WSJ.com free.
