(CNN) -- Media tycoon Rupert Murdoch expects News Corporation-owned newspaper Web sites to start charging users for access within a year in a move which analysts say could radically shake-up the culture of freely available content. Murdoch said the existing Internet business model was "malfunctioning." Speaking on a conference call as News Corporation announced a 47 percent slide in quarterly profits to $755 million, Murdoch said the current free access business model favored by most content providers was flawed. "We are now in the midst of an epochal debate over the value of content and it is clear to many newspapers that the current model is malfunctioning," the News Corp. Chairman and CEO said.
